The magnetic flap level gauge (indicator) is installed in the appropriate place, such as the side or top of the tank. The working goal of the level gauge is to indicate and control the liquid level in the tank. The drain valve is determined according to its own needs. Whether to install. The indicator is composed of white and red (green) magnetic sheets. When the magnetic float in the body tube rises with the level gauge, the color sheet will be turned over, and the liquid level height can be displayed immediately, and the liquid level height can be displayed immediately, and the output is It is a switch or analog signal. It is suitable for high temperature, high pressure, corrosion resistance and other occasions. It can be displayed on-site and remotely controlled. The measuring tube is made of seamless steel pipes, and the connecting pipes are welded by pulling holes, and there is no internal scratches. The installation method can choose side-mounted and top-mounted, and the bottom of the body is sealed.
At present, the anti-corrosion magnetic flap level gauges on the market are classified into stainless steel lined with PTFE, stainless steel, polypropylene (PP) or polyvinyl chloride (PVC) according to the production materials. The strongest anti-corrosion performance is the stainless steel-lined PTFE-lined type, but the stainless steel-lined PTFE magnetic flap level gauge also has the highest price, because the PTFE material is not only expensive but also generates a lot of hazardous gases at high temperatures. The manufacturing process High standard. If the working temperature is below 90℃, it is recommended to use PP or PVC type. It can be used on acid and alkali liquids such as hydrochloric acid, sulfuric acid, nitric acid, sodium hydroxide, etc., but the price is much cheaper than tetrafluoroethylene.
Do not allow magnetites to approach the level gauge, otherwise it will affect the up and down movement of the magnetic float. In order not to damage the float assembly during transportation, the float assembly is taken out of the main tube of the level gauge before leaving the factory. After the level gauge is installed, open the bottom drain flange, and then reinstall the float assembly into the main body. Inside the tube, pay attention that the heavy end of the float assembly is facing upwards and cannot be installed upside down.
The magnetic level gauge is a contact measurement, and the material of the liquid should be considered when measuring. This kind of medium must be anti-corrosion. If remote transmission is not required, no power supply is needed, but if remote transmission is required, power is also required. The installation is generally flanged butt, if the site conditions permit, it is not too troublesome. Its biggest advantage is that it is intuitive. For other particularly volatile media, ultrasonic waves are not suitable for use, and magnetic flaps are more suitable. There are also some mediums that require explosion-proof measurement, and it is also good to use a magnetic flap.
