How to master the key points of correctly installing and using immersion static pressure level gauge

The RZ series static pressure immersion level gauge is based on the principle that the static pressure of the measured liquid is proportional to the height of the liquid. It uses the piezoresistive effect of diffused silicon or ceramic sensitive elements to convert the static pressure into an electrical signal. After temperature compensation and linear correction, it is converted into a 4-20mADC standard current signal output. The
 
RZ series static pressure immersion level gauge has good stability and high precision. The sensor part can be directly immersed in the liquid, and the transmitter part can be fixed with a flange or a bracket, which is extremely convenient to install and use. Solid-state structure, no moving parts, high reliability, long service life, high-precision measurement can be performed from water, oil to high-viscosity paste, and it is not affected by the foaming, deposition, and electrical characteristics of the measured medium. Wide range of temperature compensation. The static pressure immersion level gauge has power supply reverse polarity protection and overload current limiting protection.
 
Precautions for the use and installation of static pressure immersion level gauges:
　　1. The level transmitter should be restored to its original packaging during transportation and storage, and stored in a cool, dry, and ventilated warehouse.
　　2. If any abnormality is found during use, the power supply should be turned off, the use should be stopped, and inspection should be carried out
　　. 3. When connecting the power supply, the connection should be made strictly in accordance with the wiring instructions.
　　
How to install the static pressure immersion level gauge:
　　When the level gauge should be installed in a static deep well or pool, a steel pipe with an inner diameter of about Φ45mm (with several small holes at different heights so that water can enter the pipe smoothly) is usually fixed in the water, and then the static pressure immersion level gauge is placed in the steel pipe for use. The installation direction of the transmitter is vertical, and the immersion installation position should be away from the liquid inlet and outlet and the agitator. In occasions with large vibrations, steel wire can be wrapped around the transmitter to reduce shock to avoid breaking the cable. When measuring the level of flowing or stirred liquids, a steel pipe with an inner diameter of about Φ45mm (with several small holes at different heights on the opposite side of the liquid flow direction so that water can enter the pipe smoothly) is usually fixed in the water, and then the static pressure immersion level gauge is placed in the steel pipe for use.

Regarding the solution to the anti-interference problem of static pressure immersion level gauge , the immersion level gauge has good stability, high precision, and is quite convenient to install and use. It will be affected by many factors in daily use. In order to enable users to better use the immersion level gauge, the following methods will be shared with you.
 
　　First of all, everyone used the traditional method to solve it, but it did not work very well. For this traditional method, that is, when measuring the liquid level of a small water tank on the equipment, the pressure transmitter is installed at the bottom of the water tank, and the sensor line is good. But there is a problem. When water flows down from the water tank, the pressure swing below will be relatively large. According to the analysis of the data, taking out a data in 1 second, the swing displayed is relatively large, and there is a correct value in it; taking out a number in 10ms to average, the effect is not good either. How to solve it?
 
Avoid the pressure of the liquid flowing down directly impacting the probe, or use other objects to block the pressure of the direct impact when the liquid flows down; at the same time, the water inlet can be installed as a shower type, cutting a large water flow into a small water flow and spraying it down, the effect is quite good; bend the water inlet pipe mouth, so that the water inlet is slightly tilted upwards, and the water will be thrown into the air first and then fall down when it comes out, reducing the direct impact (converting kinetic energy into potential energy).
