The built-in level controller is another generation of level controller developed for automatic control of level. The built-in liquid level controller has the characteristics of automatic and accurate control of liquid level, without manual operation, stable and reliable. Built-in level controller can be widely used in petroleum, chemical industry, chemical fertilizer, rubber, medicine, ships, military, power, food and other industries of various towers, tanks, tanks, spherical containers and boilers and other equipment for the automatic control of liquid level of medium.

Main technical indicators of built-in level controller:

Range: 300 ~ 6000mm

Operating temperature: -40 ~ 200℃

Control accuracy: ≤±10mm

Medium density: ≥0.5g/cm

Pressure class: ≤22MPa

Contact power: 220V, 100mA

Working principle:

The built-in level controller is composed of body, float, flange and reed pipe, and its structure is shown in the figure. Working principle: the liquid pushes the float, and the magnet in the float pushes the reed tube to close and control the intermediate relay. Then the intermediate relay pushes the contactor to control the inlet motor, so as to keep the liquid level within a certain range, thus achieving the purpose of automatic control.
