Operating principle of the water meters

Single jet dry water meter – JS
The single-jet dry water meter consists of two main assemblies: the metering unit and the counting mechanism. The main components of the metering unit are: a body with a strainer located in the inlet channel, a vane, and a sealing plate. The main components of the counting mechanism are: a gear assembly, a barrel assembly and a counter cover. The mechanism is attached to the unit by means of an attachment ring, which at the same time can act as a seal and provides protection against tampering.
The rotor of a single-jet water meter is driven by the flow of water pushing against its vanes along the circumference and is the only moving part immersed in water. Rotor rotation is transmitted via a front magnetic coupling through a sealing plate. A dry counter, encapsulated in a separate module, totals the volume of water metered and indicates the result in digital form – easy to read. The counter is equipped with a movement indicator for automatic adjustment and verification. Thanks to the special design of the rotor bearings and the selection of corrosion- and abrasion-resistant materials, the water meter has a long service life.

Selecting the correct size of the water meter

The sizing criterion (for DN, the nominal diameter) of the water meters shall always be the operating conditions, i.e.
the minimum, mean and maximum operating volumetric flow of water. A water meter that is too large not only increases the purchase costs, but also reduces the water measurement indication accuracy when the water flow is low.
A water meter that is too small overstresses the mechanism, resulting in premature wear of the moving components. Hence, to have your water meter perform properly within its measurement range limits and maximum indication error limits, its daily operating range shall be precisely determined; this can be done based on the monthly water demand, considering maximum transient volumetric flow values.
It is recommended to choose a water meter size such that the highest anticipated volumetric flow rate in the
system corresponds to 0.45 to 0.6 of the permanent volumetric flow rate Q3 of the water meter. The permanent
volumetric flow rate values for specific water meter types are listed in Table 3.

Delivery insp ection

The water meter as supplied by the manufacturer requires inspection to verify that no external shipping damage is present, especially on the body, the threaded stubs, the counter cover, and the wiring (if the version includes a transmitter module).
Check the marking of the water meter and the condition of the clamping ring or seal, which act as legal and security features.
The following markings are placed on the counter dial, the rating plate or the body of the water meter:

•  manufacturer’s name and logo,
• type-approval certificate number,
• MID type examination marking;
• identification of the measuring instrument,
• water meter number,
• the metrological marking comprises the capital letter M and the two last digits of the production year in
• which the marking was applied to the measuring instrument,
• direction of the flow, shown with an arrow,
• V, H→ mark for vertical and horizontal piping water meters,
• H↑ mark for horizontal piping water meters,
• H/V mark for horizontal and vertical piping water meters,
• volumetric flow value, Q3 in m³/h,
• measurement unit designation in m³ (see the counter scale);
• maximum pressure loss,∆,
• maximum pressure limit: PN 16,
• manufacturer’s address

Water meter installation requirements

6.1. The installation location should provide easy access for the process of installation, removal, servicing, and reading, and be separated from rooms in use or for storage. Protected from adverse weather conditions and protected from the effects of electrical and gas installations. If there is no installation location suitable according to these criteria, the water meter can be installed in a dedicated chamber, but the installation location inside it shall be sufficiently high above the chamber bottom. The chamber must have a sediment trap or a water drain discharging to the outside
6.2. The water meter at its installation location shall not be exposed to shocks or vibration from nearby equipment in operation or excessively high ambient air temperatures, or contaminants, or flooding with water, or corrosive ambient agents. The installation location temperature shall be lower than 4°C. Protect the water meter from hydraulic turbulence, including cavitation and water rams
6.3. valves shall be provided upstream and downstream of the water meter in order to shut off the water supply in case of necessity of removal for inspection or repair, with the possibility of completely uncovering the crosssection of the supply pipe
6.4. If the water flow is expected to be contaminated during operation of the water meter install a suitable filter or trap between a straight upstream section of the piping and the upstream stop valve
6.5. To prevent the installation fastening from stressing the water meter body, it is recommended to use expansion (deflection) couplings installed on the meter’s discharge side. The coupling shall permit the reduction of the length by telescopic sliding of its sleeve
6.6. The piping route geometry at the installation location shall prevent air blocks from forming within the installation length of the water meter. The water meter must remain completely filled with water, so the water supply piping downstream of it must not have a drop in the downstream direction (see Fig. 4). It is recommended that the water supply system is routed in such a way that it can be drained by gravity using a drain cock located at the lowest point of the water supply pipe. 6.7.
Prevent overstressing of the water meter due to the attached piping or other equipment. If necessary, install the water meter on a pedestal or a bracket. The upstream and downstream piping must be properly fastened so that no component of the system shifts by the action of water when the water meter is removed or detached on one of its ends.
6.8. The installation of the water meter in the system must conform to the intended operating orientation (horizontal, vertical and oblique, as applicable by specification) (see Table 2).
6.9. When using typical connectors to incorporate the water meter, no other straight sections upstream (U0) and downstream (D0) of the unit are required.
However, if the unit is installed downstream of a double elbow, non-return valve, filter, pump or other fitting which significantly disturbs the flow profile, a straight section upstream of the unit with a length of L=5×DN (nominal diameters of the unit) (U5) and downstream of the unit with a length of L1=3×DN (D3) shall be provided (Fig.4).

Priming and commissioning

7.1. Before installing a water meter in the piping, flush the piping to remove all debris and contamination. If a filter is to be used, it shall be cleaned before the installation process. For the flushing process, the water meter shall be replaced with a straight pipe spool.
7.2. Prior to its installation do a functional test of the water meter: spin its rotor and inspect for proper rotation of the rotor or the counter pointers. Check the condition of the retaining ring or the condition of the seals.
7.3. Once the water meter has been installed, water shall be fed into the pipeline slowly and with the vents open, so that the air leaving the system does not cause excessive rotation of the water meter rotor causing damage to the rotor.
7.4. During operation, the stop valves upstream and downstream of the water meter shall be fully open.
7.5. Having completed the aforementioned commissioning tasks, verify that the water meter is operable: its reading should increase as the water flows.
7.6. During the operating stage, periodically check that the actual operating conditions meet the intended use of the water meter, especially the maximum operating pressure, temperature and flow rate values.

Maintenance, inspection and repairs

The measurement performance of the water meter will become reduced throughout its operating life. The deterioration of these properties is generally due to the aggressive action of water. Hence, every water meter, upon noticing an irregularity in operation, shall be disassembled and cleaned in order to determine the reasons for such a state of affairs. Whereas the water meter after the expiry of the conformity assessment/verification period. It shall be overhauled/refurbished in connection with secondary verification or it may be replaced with a new one.
The validity periods for conformity assessment are defined in the metrological regulations. Every time the water meter is removed from a water system, it must pass a reference indication accuracy before its disassembly and cleaning. Do not clean with agents detrimental to the materials of water meter parts. Do not clean the water meter parts with any corrosive agents or solvents (this applies specifically to plastic parts) or agents which accelerate ageing of seals.
Repairs should be carried out at properly prepared authorised service centres.
In the case of repairs involving the necessity of replacing components, only original spare parts supplied by Apator Powogaz S.A. shall be used. Once repaired, water meters are subject to inspection in accordance with current regulations.

Storage and transport

The brand-new or repaired water meter shall be kept with the counter upwards or to the side in an indoor room free from all corrosive vapour, odours, etc. agents which might be detrimental to the water meter. The indoor storage temperature shall be between 5°C and 30°C at a relative air humidity not exceeding 80%. Protect the device in storage and during transport from vibration and shock which may damage the enclosure or internal components. Transport the meter in sheltered vehicles, in its original packaging or its substitute, whichever fully protects the meter from damage.

Troubleshooting

If the counter does not indicate when water is flowing through the water meter, check whether the rotor is obstructed due to contamination. If, after any cleaning, the water meter does not function and in any other case of non- functioning, the water meter shall be submitted for repair with a description of the abnormality. If the pulse transmitter module fails, report this to the supplier. If the troubleshooting is ineffective despite any instructions received from the supplier, have the water meter repaired.

Safety and environmental requirements

11.1. The water meter is a measuring instrument which is safe to use, provided it is installed properly and operated according to its intended use.
11.2. Direct residual hazards exist during installation servicing and operation of the water meter:

• mechanical hazards:
  □ fall during improper handling
  □ water leaks, leading to flooding of the water meter due to improper installation or a water pressure exceeding the rated MOP;

• thermal hazards:
  □ burns from touching the water meter while it is in operation or a leak of hot water.

11.3. The mechanical hazards are reduced by the outer geometry of the water meter which facilitates handling. The thermal hazards can be prevented by application of dedicated guards.
11.4. The installation and servicing of the device requires a suitable location with firm ground that will not cause a hazard of falling.
11.5. The water meter components are not harmful to human health or the environment. All cold water meters are delivered with hygiene certificates for use with drinking water.
11.6. The use of counter seals and other design solutions protect the water meter from the negative effects of condensation on the correct indication reading or the operation of the pulse transmitters.
11.7. Classification of environmental conditions

• Classification of mechanical environment conditions: Class M1 (ref. Polish Regulation Dz.U. 09.06.2016)
• Classification of mechanical and climatic environmental conditions: 5°C to 55°C in confined or open locations (ref. Polish Regulation Dz.U. 09.06.2016).
• Classification of electromagnetic environment conditions: Class E1 (ref. Polish Regulation Dz.U.  06.06.2016)
