How to install a liquid level transmitter

How to install a liquid level transmitter

Nowadays, liquid level measurement and control are required in fields such as petroleum, chemical, power plants, urban water supply, and hydrological exploration. The use of input type liquid level transmitters is becoming more and more widespread. Their products have high accuracy and small volume, and can be directly input into the liquid to measure the liquid height from the end of the transmitter to the liquid level, which is convenient to use.

So how should this input type liquid level transmitter be installed?

1、 Installation in still water (deep well, water tank, liquid injection, etc.)

Installation Tip:

1. When measuring the static fluid level in an open container, place the level transmitter vertically at the bottom of the container, and fix the cable and junction box connecting the transmitter at the opening of the container.

2. When the viscosity of the medium is high (such as in a sewage tank), a sleeve or bracket can be installed to ensure that the transmitter can be placed at the bottom of the container.

3. When installing outdoors, the transmitter junction box should be placed in a well ventilated and dry place as much as possible to avoid direct exposure to strong light and rain, which can cause high housing temperature or water ingress, thereby damaging the internal circuit board.

2、 Installation in dynamic water (rivers, lakes, etc.)

Installation Tip:

1. When measuring the water level in flowing water, if the medium fluctuates greatly, a steel pipe with an inner diameter of about 5 centimeters can be inserted into the waterway. Several small holes with a diameter of about 5 centimeters can be opened at different heights in the opposite direction of the water flow direction of the pipe that invades the water, allowing water to enter the pipe. The cable and junction box can be fixed at the outlet of the pipe.

2. When the water channel medium fluctuates and sediment is large, it is also possible to filter sediment and eliminate the adverse effects of dynamic pressure and waves by installing damping devices to ensure measurement accuracy.

3. When installing the product in areas with frequent lightning strikes, it is recommended to indicate "lightning protection" when ordering. At the same time, it is suggested that users install lightning protection devices on site and ensure reliable grounding of the product and power supply to reduce the probability of lightning damage to the transmitter.
