Detailed Product Description

WT-400 series multi-flow rate totalizer(can with temperature and pressure compesation function)

Dimention: width×height×depth=80×160×125mm  

Cut-out:76^+0.7×152^+0.7

application scope

cooperate with various sensors/transducers,

measuretotalize,display, alarm control ,transform output,

data receiving and communicate the flow parameters such as liquid,steam,natural gas,and general gas.

Function and feature:

Total automatic control,pressure compensation caculating,the compensation ways can be set at any way.

Linearity totalizing and radication totalizing setable.

Multi parameter display such as instant flow rate,total flow rate,temperature and pressre .

Small signal drop out function.dropping out ranges 0-0.5%selectively.

Totalized flowrate value can be reset by pushing button. The reset operation can be locked.

Off-power protection function,the total flow rate can be maintained more than 5 years as a result of off-power. All of the preset value is maintained for ever after off-power.

Advanced modular structure, with a powerful instrument chip, the functional combination and

system upgrade are very convenient.
