In industrial chemical plants, external ultrasonic level meters and ultrasonic level meters are often used to measure the liquid level of storage tanks and reactors because of the following advantages.
First, easy to install, do not need to open the tank top can be installed, you do not need to dry the liquid in the tank, to solve the cumbersome process of installing flammable liquids.
Non-contact measurement. Without touching the liquid, it can be measured. The density and viscosity of the liquid do not affect the measurement.
In the large number of chemical enterprise storage tanks that we contact, because of the lack of a comprehensive understanding of the ultrasonic level meter, the following common mistakes have been made during use.
1. Only consider explosion-proof without considering anti-corrosion requirements
Chemical enterprises in the selection of ultrasonic level meter, generally consider the requirements of explosion-proof, because most are flammable and explosive liquids. It is common to consider anti-corrosion on hydrochloric acid, sulfuric acid, and hydrofluoric acid liquids. In fact, when measuring toluene, xylene, alcohol, acetone and other organic solvents, it is also necessary to consider anti-corrosion, and most organic solvents are soluble to ordinary plastic materials. We’ve seen probes dissolved at multiple chemical sites, just like glue.
External ultrasonic level gauges can be used in harsh environments:
Can measure any pressure of the liquid.
Highly toxic liquids can be measured.
Can measure highly corrosive liquids.
It can be measured for liquids requiring sterility or high purity.
Can measure flammable, explosive, easy to leak, easy to pollute liquid.
2 Use ultrasonic level gauges on highly volatile liquids.
Chemical storage tanks, there are many organic solvents, such as: toluene, xylene, alcohol, acetone and so on. Most organic solvents are highly volatile. The ultrasonic level meter is an ideal measurement tool for corrosive, stratified or acid-alkali wastewater. Ultrasonic level meter can measure the media including hydrochloric acid, sulfuric acid, hydroxide, waste water, resin, paraffin, mud, lye and bleach and other industrial agents, widely used in water treatment, chemical, electric power, metallurgy, petroleum, semiconductor and other industries.

secure
In the measurement of toxic, corrosive, pressure, flammable and explosive, volatile, easy to leak liquids, because the measuring head and instrument are outside the container, so installation, maintenance, maintenance operations do not contact the liquid and gas in the tank, very safe. Even when the meter is damaged or in repair condition, there is no possibility of causing leakage.
Environmental protection
In the measurement of toxic and harmful, corrosive, pressure, flammable and explosive, volatile, easy to leak liquid, because the measuring probe and instrument are outside the container, so the installation, maintenance, maintenance operation does not contact the liquid and gas in the tank, very safe, and does not pollute the environment, is a environmental protection instrument.
