GIWS... - Wire-Spring - Water Gate Indicator - Takuwa Vietnam - STC Vietnam

Water Gate Opening Indicator

Water gate indicator is important equipment for control of water gate on dam and river weir etc.

We have a lineup of indicators and converters which are suitable for purpose and site condition.

Wire-Spring Type (GIWS Series)

GIWS Series is water gate opening indicator by measuring a length of paying-out of wire which is directly connected to the gate body, and  wire loosening will be rolled up by a spring.

Can be installed at existing gate regardless of water gate hoisting-device. 

Measured data is indicated by hand on large scale board, and optional 4 type sensors (Synchro transmitter, A/D-converter, Potentiometer, Limit switch) are able to mount as option for output signal.

It is widely used because of high durability against vibration, temperature and noises.
