Flow totalizer


 Flow totalizer

YJ-908 Flow totalizer With various flow sensors or transmitters, temperature sensors or transmitters and pressure transmitters, intelligent flow totalizer can measure and display, accumulate calculation, alarm control, transmit output, data acquisition and communication for various liquid, steam, natural gas, general gas and other flow parameters.


 

YJ-908 Flow totalizer Product features:

1. The intelligent flow totalizer can automatically calculate the temperature and pressure compensation in full range, and the compensation mode can be set arbitrarily  
two
, linear product and square root product can be set arbitrarily
three
, instantaneous flow, cumulative flow, temperature, pressure and other parameters display
four
Small signal resection function, resection range 0-5% Optional
five
The accumulated flow value of the intelligent flow totalizer can be reset through the panel button, and the reset operation can be locked
six
Power down protection function, the accumulated flow value power down holding time is greater than five All set values remain permanently after power failure
seven
Intelligent flow totalizer advanced modular structure, with powerful instrument chip, function combination, system upgrade is very convenient
