                                      GSM ultrasonic water meter

Application: 

GENERAL

The water meter is adapted by the company's newly-developed unique advanced transit time measurement technology, with remarkable features of low power consumption, wide measuring range ratio, stable and reliable measurement. In the structure, the components take the IP68 program, that is, each component is of an IP68 protection level, to ensure long time operation though water in the inside meter. The wireless power and various communication interfaces can be matched to the meter to achieve remote meter reading.

 

♦ KEY FEATURES

1 Double beam ultrasonic sensors for high accuracy and reliable operation 
2 Less than 0.01 m/s starting velocity
3 Multi line 9 digital LCD accumulative flow and 4 digital for instantaneous flow
4 Support MODBUS, M-BUS, HART communication protocol 
5 Built-in batch controller and time accumulator
6 Built-in Lithium battery for 6 years life expectancy

7 Output: Two way isolated pulse output (pulse equivalent and output pulse can be

arbitrary programmed); two-wired system 4-20mA output
