ZENNER ZSUR Stealth Ultrasonic Residential Meters Installation Manual
Product Description
ZENNER ZSUR Ultrasonic Residential Water Meters are designed for cold water
applications up to 122°F.
Intended purpose
- For the consumption measurement of drinking water up to 122°F.
- For the consumption measurement of non-potable water up to 122°F.
Comment
This installation manual is intended for qualified meter installers only.
Basic installation steps are therefore not described. In order to ensure a
proper flow measurement, the meter must be completely filled with water at all
times.
Permissible installation positions
Activating the Meter
Upon delivery, the display of the meter will ar-rive in “sleep mode”. To
activate the meter, simply fill the meter with water for ten seconds. This
will move the meter into active reading mode. During the installation, all air
must be ventilated from the meter and the meter must be completely filled with
water in order for activation to be achieved.
Once the meter has been activated, an automat-ic display check takes place
(segment test). The segment test is represented by three flashes of all
segments on the display indicator and is re-peated every 60 seconds during
operation.
Readout options of the ZSUR meter via the NFC (Near Field Communication)
Interface Cable
The following data can be directly read from the measuring instrument via the
NFC interface, e.g. with NFC-capable smartphone:
- Meter ID (serial number)
- Current consumption value or total volume in the case of an overrun
- Up to 15 previous month’s values
- Software version
- Alarms or error messages
The meter can be retrofitted with NDC modules, or ordered with a factory- fitted module.
Meter Installation
- To achieve optimal measurement results, (3) times the pipe diameter should be allowed on the inlet and (2) times the pipe diameter should be allowed on the outlet side of the meter. However, ZSUR Ultrasonic Residential Meters are designed to be installed without straight sections in front and after the meter and still meet AWWA accuracy standards.
- Clean and flush the service line thoroughly on the inlet side of the meter before in-stalling.
- The pipe cross section should not be reduced directly in front of and behind the me-ter.
- Valves or other flow regulators should be installed, where possible, behind the meter.
- The meter should be installed, where possible, at the deepest point of the pipe installation insuring air is not entrapped within the meter and the meter body is always com-pletely water filled.During installation, ensure the flow arrow indicator on the meter housing is pointed to-ward the customer’s side of the service line. Install using new gaskets.
- To insure unrestricted flow of water through the meter, use the proper size and type of gaskets. Connections should only be sufficiently tight to seal; do not over-tighten. Flange gaskets must not extend into the pipe.
- If necessary, the meter should be protected by a strainer. This will keep foreign matter, such as stones or debris, from entering the meter and potentially cause damage.
- The meter is designed for use in a frost-proof location with ambient temperature not to exceed +130°F and with water tempera-tures not to exceed +122°F .
- To prevent damage during the installation process, ensure that the meter is slowly filled with water.
Display description
- Segment test display
- Consumption value
- Flow direction display in forward flow direction
- Flow direction display in return flow direction
- 4-digit flowrate display in Gpm, Cfpm or
- Alarm or error messages (are saved in the data logger and can be read out via the NFC interface)
- External power supply: Symbol is activated once a communication module is connected via the NFC interface
- Battery capacity display: Symbol is activated aprox. 180 days prior to fully dis- charged battery. The battery capacity is 12 to a maximum of 15 years (depending on the ambient conditions as well as use and configuration of a connected NDC module)
- Data transfer display: Symbol is only activated for the connected NDC module

Overrun event
In the event of an overrun, all leading zeros are displayed in the consumption
display (display 00000.0000, 000000.000, 0000000.00 or 00000000.0). The actual
consumption is fully recorded in the internal memory and can be re-trieved via
the NFC interface.
Caution
In the case of exceeding the max. overload flowrate (Q4m), the flowrate
display is deactivated to protect the measuring instrument (set to zero).
While the flowrate is exceeded, the consumption progress is not registered.
The exceeded overload is stored a an “Alarm or error message” in the data
logger with details of the date and length of exceedance.
