Project Overview

The submersible liquid level transmitter is directly put into the medium to be measured, and is very convenient to install and use. Solid structure, no moving parts, high reliability, long service life. High-precision measurements can be made from water, oil to pastes with higher viscosity, and are not affected by bubbling, sedimentation, and electrical characteristics of the measured medium. Wide range temperature compensation. Please see below for the working principle of the input liquid level transmitter.

1. The basic working principle of the input liquid level transmitter is hydrostatic liquid level measurement.

In liquid media, the pressure generated at a certain depth is generated by the weight of the medium itself above the measuring point. It is proportional to the density of the medium and the local acceleration due to gravity. The proportional relationship between them is reflected by the formula P=ρGH. Where P=pressure, ρ=medium density, G=gravitational acceleration, H=depth of measuring point. Therefore, the physical quantity measured by the input liquid level meter is actually pressure, which can be understood through the calibration unit of the input liquid level meter, MH2O. The actual liquid level must be obtained through conversion after knowing the two parameters of density and gravity acceleration. Such conversion is usually performed through secondary instruments or PLC in the industrial field.

2. Advantages and Disadvantages of Submersible Liquid Level Transmitter

1. Main advantages:

High measurement accuracy; easy installation; signal can be transmitted remotely for remote control ;

It can resist the corrosion of various media by selecting different materials; it is suitable for explosion-proof occasions; the price is moderate.

2. Disadvantages:

The measurement signal needs to be converted; it cannot measure the temperature of high-temperature media exceeding 125°C; the density of the measurement medium must be uniform.
