This product can directly display the instantaneous and cumulative flow. The built-in EEPROM digital memory makes sure that the data will not lose in case of power failure. With different built-in algorithms, the product supports weirs or notches of different standards in various countries and can be widely used for measurement or monitoring of total water drainage. The measurement result is not affected by the water quality. It can be connected with various systems and, with GPRS wireless module, realize the industrial remote monitoring and control. 


1.With the die casting aluminum alloy waterproof and explosion-proof shell, be explosion-proof and safe.

2.For the circuit design, high-quality power modules are selected from the power supply and highly stable and reliably imported devices are used as its components. It can fully replace imported foreign meters of the same type. 

3.Patent sonic-wave intelligent technology software can make intelligentized echo analysis. It needs neither debugging nor other special steps. This technology has functions of dynamic thinking and dynamic analysis. 

4.Our sonic-wave intelligent patent technology improves the precision (up to 0.3%) greatly. It can resist various interference waves. 

5.This product is a kind of non-contact instrument. As it doesn’t contact the liquid directly, the failure rate is low. This product is designed with different installation methods. The user can make calibration independently as described in this manual. 

6.All incoming and outgoing lines have lightning proof and short-circuit proof functions.
