remote control liquid level controller

remote control liquid level controller is a float type liquid level controller that can remotely control the liquid level in the display cooler container to ensure the normal operation of the refrigeration device. The sensing element of the remote level gauge must be used in conjunction with the actuator and installed in the pipeline.

Principle of action: When the float rises and falls with the change of the liquid level of the float chamber, it drives the core iron to rise and fall in the acting coil. When the core iron rises to the highest position, the current through the active coil is the smallest: when the core iron drops to the lowest position, the current through the active coil is the largest. After this maximum or minimum weak current signal is amplified by the transistor amplifier, the contact of the intermediate relay changes position. Only when the controlled liquid level reaches the lower limit or the upper limit, can the contact of the intermediate relay change position. When the liquid level reaches the lower limit, the contact of the intermediate relay is closed at point a (point b is disconnected), and the solenoid valve connected to the 6th and 7th terminal blocks is energized and opened (the solenoid valve connected to the 7th and 8th terminal blocks Turn off the power) to control the liquid level of the float chamber. The float chamber of the liquid level controller should be installed vertically on the controlled liquid container, with the acting coil on the upper part. At the same time, the orifices of the connecting flange on the controller should be connected to the liquid container with steel pipe, and the installation height should be the same as that of the container. Suitable for medium controlled liquid level. In addition, there are two knobs in the controller electrical box, which can respectively adjust the position of the highest or lowest liquid level and the distance between the high and low liquid levels. The display cooler liquid level controller generally has a lift change range of 40mm. When the liquid level in the container has a large change range, generally there are two upper and lower remote control liquid level devices in the low-pressure circulating liquid storage tank. The lower level device is used To control the standard liquid level, the upper level gauge is used as a warning level alarm.
