Technical Specification

Flow Sensor
The flow sensor is a device used to measure the velocity of flow by using the principle of ultrasound. It can measure the average velocity along the path of an emitted beam of ultrasound by averaging the difference in measured transit time between the pulses of ultrasound propagating into and against the direction of the flow. The flow measurement is based on an acoustic wave time of flight principle. The flow meter body is equipped with 2 ultrasonic transducers facing 2 acoustic reflectors.

Flow sensor data:

Operations on how to display
Users may cover the button to read the meter information such as Accumulated volume, current flow rate, etc.
To save the battery, the meter switches to sleep mode (display off) if the button is not covered for approx. 3 minutes. It can be woken up by covering the button approximately 3 seconds.

The following information is displayed in order by short covering the button: accumulated flow, instant flow, date, time, accumulated working time, Meter ID, address, meter type, software version No., checksum, etc.

Menu List (User Loop)
Cover the button for 5 seconds and holding it on will bring up the four menus for users to select.

Main Menu
Shortly covering the button to display items under the Main Menu one by one in the following order to check the measurement data:

Menu E
Shortly covering the button to display items under Menu E one by one in the following order to check the meter information:

Menu I
This Menu shows history date records of last 24 logs (month as example). Cover the button to select the log number, then the log number, log reading will be displayed in turn.

Menu F
The following diagram shows Menu F (Calibration mode only). In F mode, Accumulated flow value is able to reset automatically, when flow is zero and starts to exceed the preset value then the current accumulated value is clear to zero. Also the value can be reset by long-covering the button (over 5 seconds). The meter exit the calibration mode if no operation for 2 hours.

Note: Preset value is pre-set to make sure zero calculation when there’s no water flow in the pipe, usually the value equals to 0.1% of Q3.

Error and Warning
The meter constantly performs self-diagnosis and can display various faults. Visual indication on the LCD display in the event of a warning. Permanent visual indication on the LCD:

Fault / Meaning / How to handle the error

1. Low battery Communication circuit to be checked
2. Empty Pipe Fulfill the pipe with water, no air bubble.
3. Reverse Flow Reverse the water pipe.
4. Over Range (High Instant flow rate) Lower the instant flow rate, or change a higher Range water meter.
5. Water Temperature Error Lower the water temperature
6. EE Memory Error Change circuit board.
7. Reserve –
8. Reserve –
9. Leakage Alert Find leakage point

• A Burst Alert Lower the instant flow rate, or change a higher Range water meter.
• B Tamper Alert Resolve alert or reset alert
• C Freezing Alert Raise the water temperature
