Liquid Turbine Flow meter

Overview:

SLW Liquid turbine flow meters have the features: high accuracy, good repeatability, convenient installation/maintenance, simple structure etc. They can be used to measure pure liquid, such as water, gasoline, diesel, etc.The working Principle of SLW liquid turbine meter is that Liquid flows through the turbine housing causing an internal rotor to spin. As the rotor spins, an electrical signal is generated in the pickup coil. This signal is converted into engineering units (liters, cubic meters, gallons etc.) on the local display where is applicable. Optional accessory modules can be used to export the signal to other equipment.
