Overview
The WRTF series flow switch is mainly used for flow monitoring and switch output in pipelines. Its solid structure and stable performance can be widely used in the cooling and lubrication systems of compressors, motors, generators, rolling mills, conveyors, and other machines. When the flow exceeds or falls below the preset switch point, it can output a signal. At the same time, this preset switch point can be set at any position within the range, and it can be easily adjusted under installation conditions.

1WRTFflow switchIntroduction
WRTFseriesflow switchMainly used for flow monitoring and switch output in pipelinesIts solid structure and stable performance can be widely applied In the cooling and lubrication systems of compressors, motors, generators, rolling mills, conveyors, and other machines. When the traffic exceeds or falls belowPre value switch When clicked, it can output a signal. At the same time, this preset switch point can be set at any position within the range, and this switchPoint can be on Easy to adjust under installation conditions.

WRTF184flow switchThe basic type is composed of GType indicator group Cheng. Corresponding to the measurement range1/10The graduated dial can be easily Observe traffic. At the same time, this type offlow switchIt can be conveniently Adjust the switch alarm point without interrupting the flow in the pipeline.
WRTF181-WRTF183flow switchCan be done byAType orGType finger Composition of indicators. Corresponding to the measurement range 1/h ，1/min ，m3/h The equally divided circular dial and pointer can facilitate the observation of flow rate. At the same time, this type offlow switchYou can also easily adjust the switch Alarm without interrupting the flow in the pipeline.

measurement systemC（WRTF181and WRTF182）By conical tube and Composed of freely movable baffles, it is suitable for handling pure liquids Take measurements.
When the fluid passes through in a specified directionflow switchTime measurement gear The plate generates displacement based on the flow rate, and the displacement is related to the highly stable spring Elasticity is in equilibrium, and each determined flow corresponds to a flat state Balance position. Sensors installed in isolated environments of measurement systems Magnetic coupling indicates flow rate and outputs control signals.
Magnetic lever capable of freely rotating on PTFE sealing ring Capable of preventing particles from entering the medium and equipped with calibrated control magnets Inside the cabin with springs.
measurement system ESuitable for measuring particles containing small particles or those that may The medium blocking the pipeline (only applicable to)WRTF181-182）.
