Product overview
Oil flow indicator (referred to indicator below) is the device to monitor and indicate the variation of oil flow in the oil circulation cooling system of transformer. Specifically, it is used to indicate whether the rotation of oil pump is correct, the valve is turned on, the pipeline is clogged. The relay will send an alarm signal to the control unit when the oil flow reaches the operating value.
Advantage
1.Vibration-proof;
2.Sensitive;
3.Stable and reliable;
4.Precise.
Use conditions
Ambient temperature: -30℃~+40℃；
Relative humidity: less than 90% at +25℃;
Oil temperature: less than 90℃；
Location：areas where there is no strong vibration and bump around;
Type selection: the operating characteristics of indicator should be consistent with the oil flux of transformer cooling system.
