Installation, connection and anti-interference of input leve
Proper installation and wiring of input level transmitter
Notes for the use and installation of the input level transmitter:
1. When the liquid level transmitter is transported and stored, the original packaging should be restored and stored in a cool, dry and ventilated warehouse.
2. If any exception is found during use, power off, stop use, and check
3. Strictly follow the cable connection instructions when connecting the power supply. Sonar level gauge
How to install the input level transmitter:
The liquid level meter should be installed in the static deep well, pool, usually the inner diameter of about 45mm steel pipe (different height of a number of holes, so that water smooth into the pipe) fixed in the water, and then put the liquid level transmitter into the steel pipe can be used. The installation direction of the transmitter should be vertical, and the installation position should be far away from the liquid inlet and outlet and agitator. In the use of large vibration, can be wound on the transmitter steel wire, the use of steel wire shock absorption, so as not to break the cable. When measuring the liquid level of the flowing or stirred liquid, the steel pipe with an inner diameter of about 45mm is usually fixed in the water (a number of holes are made at different heights on the opposite side of the liquid flow, so that the water can enter the pipe smoothly), and then the input liquid level transmitter can be used in the steel pipe.

How to solve the anti-interference problem of the input level transmitter
The plund-type liquid level transmitter has good stability, high precision and easy installation. It can be affected by many factors in daily use. In order to enable users to better use the input level transmitter, for the majority of consumers to provide a solution.
First of all, everybody used the traditional method to solve it but it didn't work very well. For this traditional method is to measure the liquid level of a small tank on the equipment, the pressure transmitter is installed at the bottom of the tank, the sensor line is good. But there is a problem, when the water above the tank comes down, it will make the pressure below swing relatively large. From the analysis of the data, with 1 second to take out a data, the display of the swing is relatively large, and there are correct values; Taking a number and averaging it over 10ms is not good either. How to solve it?
The solution of anti-interference problem of input level transmitter:
Avoid the direct impact of pressure on the probe when the liquid flows down, or use other objects to block the direct impact of pressure at that moment when the liquid flows down;
Put the water inlet into a shower, cut off a large stream of water into small water spray down, the effect is good; By bending the inlet so that it is slightly upward, the water will be thrown first into the air and then back down, reducing the direct impact (converting kinetic energy into potential energy).
