Liquid Turbine Flow Meter
LTB series turbine flow meter have the features: high accuracy, good repeatability, convenient installation/maintenance, simple structure etc.
Liquid flows through the meter tube which drive the internal rotor rotating to generate an electrical signal in the pickup coil, this signal is converted into engineering units (liters, cubic meters, gallons etc.) on local display. Optional accessory modules can be used to output the signal to other equipment.
