Ultrasonic Water Meter

Technical Characteristics Low power consumption, digital process technology with stable and permanent PiezoSeal tm sensor. Accuracy Conforms to EN1434 Class 1; Better than 1.0% (r); Class b according to ISO4064-1 Repeatability Better than 0.2% (r) Sensitivity/Dead band 0.0003m/s Display 1) total flow, flow rate, velocity, working time and date

2) signal intensity, quality and battery status Connection and output 1) RS485 (ModBus available)

2) 4-20mA output

3) gprs wireless module available

4) OCT(open collector output) for total flow

All the output need external power supply (5VDC-24VDC) connected to 24VDC +, -, terminals. Operation Magnetic pole with reed and inside keypad available Sampling period 0.5s Fluid Water or other liquids of -20℃～121℃ Environment temperate -25℃～65℃ Other functions 1) Automatic circle display of commonly used value can be programmed.

2) Fault self-diagnosis detection, fault indicator.

3) Baud rate: 300，1200，2400，4800，9600, parity available

4) Store data of total flow of last 35 months

5) 8 digits negative/positive totalizes, inside 64 digit calculating

6) Data storing when power off

7) Other programmable functions Power Supply 1) 3.6V lithium battery. Can work with 3.1V.

2) 9-28VDC consumption 1) For recording data twice per second for pipe DN300, the consumption is 0.18mW

2) Water meter will enter into energy saving mode when the pipe is empty, consumption is only 30% as normal working. Enclosure class IP68, Can work under water, Nitrogen test for tightness has been already done in our laboratory. Pipe size Suitable for pipe size DN40-600, DN600-1000 are hot-tapped insertion type. Flange connection Flanges according to din, ansi, jis or other std. customer specified for smaller pipe size, pls contact factory.
