BLZ series oil flow indicator is a kind of alarm device which can monitor the change of oil flow. Its design and manufacture conform to the Chinese standard JB/T8317-2007. < Oil flow indicator Transformer Cooler > Standard.

This product can be used to monitor the operation status of OFAF cooler and OFWF cooler, as well as whether the oil pump is reversed, whether the valve is opened, and whether the pipeline is blocked. The product signals when the oil flow decreases to the set value.

Bellows flexible connection type oil flow indicator can meet the required clearance requirements when disassembling and assembling accessories. In addition, it can improve the sealing performance, reduce vibration and noise, and flexibly connect the cooler and transformer oil pump without changing the installation size. The flange connected with the corrugated pipe can be rotated freely and installed along the radial direction, which is convenient for field installation.
