Product details

The LWGY turbine flow sensor is a precision flow measurement instrument suitable for measuring low viscosity media such as water, diesel, gasoline, etc. It can be used to measure the flow rate and total amount of liquids when paired with corresponding flow accumulation instruments. Widely used in the fields of petroleum, chemical, metallurgy, scientific research and other metrology and control systems.
Sensors come in various forms such as ordinary, high-precision, and wear-resistant (hard alloy) types. There are two types of amplifiers: regular and explosion-proof. This sensor can also be used in conjunction with the LRT-I field flow meter (powered by lithium batteries, with battery replacement after 1 year).
