What should be paid attention to when selecting water level gauge for fire pool?

The DPSH-A liquid level display controller produced by Wuxi Sifang Electric Instrument Co., Ltd. is suitable for the detection, display and control system of water level, oil level and liquid level in various industrial enterprises, commercial and civil buildings, high-fire water tanks and pools.

First, the product principle:

The probe with built-in liquid level transmitter can be directly put into the measured liquid, which can detect and display the liquid level height in time. When the water level in the water tank pool drops to the set lower water level value, the liquid level display controller sends out an instruction to instruct the pump valve to open water supply, and when the water level reaches the set upper water level value, the liquid level display controller sends out an instruction to instruct the pump valve to close and stop water supply. Similarly, if necessary, the liquid level display controller can also instruct the water pump or electric valve to do the opposite operation.

Measure and display the liquid level height of the measured medium, and display it in digital form (accurate to 0.5 level). The measuring and displaying distance can reach 4000 meters. The alarm values of upper and lower water levels can be set at will according to users' needs (generally, two alarm points can be set, one high and one low, and four alarm points can be set when necessary, and the upper limit, upper limit, lower limit and lower limit can be set). When the liquid level is higher or lower than the alarm point, there is relay output, which can automatically send out alarm signal or control signal.

Select functions and other control instructions (specified when ordering)

You can choose 1, 1 or two or more display positions, which can simultaneously display the liquid level height of the measured liquid.

2. You can choose sound and light alarm. When the water level in the water tank is higher or lower than the set alarm value, the controller gives an audible and visual alarm. Optional alarm mute function.

3. You can choose 4-20mA signal output or communication 485 signal output (extra) to communicate with the computer remotely.

4. It can cooperate with solenoid valve or user's existing pump control cabinet to automatically complete the on/off action. Optional function, extra charge.

Second, the composition of the product:

It is composed of input liquid level transmitter (probe), instrument display control box and actuator (solenoid valve, water pump and electric valve).

The put-in liquid level transmitter (probe) is put into the measured liquid as a field primary instrument, and the signal transmission can reach 4000 meters through wires. If it is a highly corrosive liquid or high-temperature hot water medium, it should be noted when ordering, and it is equipped with an appropriate medium probe.

Display and control instrument box: intelligent digital display adjusting instrument, which can display the liquid level height of the measured liquid in time and set the upper and lower alarm points of the water level of the water tank. Size of control box: 250× 300×150mm (width× height× thickness). The instrument control box can be fixed on the wall of the control room or duty room. (The distance between the liquid level transmitter and the instrument box can reach 4000m)
