Description
The LWGY turbine flowmeter sensor is a flow measurement instrument, which can be used to measure the flow and total volume of liquid in a matching with the corresponding flow integrating instrument. Widely used in petroleum, chemical, metallurgy, scientific research and other fields of measurement, control system. Turbine flowmeter sensors equipped with sanitary joints can be used in the pharmaceutical industry. The integrated turbine flowmeter structure is designed for explosion proof, which can display the total flow, instantaneous flow and flow full percentage. The battery adopts lithium battery, the battery life of the single-function integrated meter can reach more than 5 years, and the battery life of the multi-function display meter can reach more than 12 months. The meter head can display a large number of flow units, including cubic meters, gallons, liters, standard cubic meters, standard liters, etc., can set the fixed pressure, temperature parameters to compensate the gas, pressure and temperature parameters do not change, can use the instrument for fixed compensation product.
Technical performance of liquid turbine flowmeter
For the higher viscosity of the hydraulic oil, oil, * specification can be used for real flow calibration.
