What is a submersible level transducer?

Submersible Level Transducer is a type of transmitter that can directly measure the liquid level by putting the sensor into the tank, water or oil.

Submersible Level Transducer can also be called “static pressure level transmtter, liquid level transmitter, liquid level sensor, water level sensor”

Working Principle of Submersible Level Transducer

Submersible level Transducers are based on the principle that the measured static pressure of a liquid is proportional to the height of the liquid. Use the piezoresistive effect of diffused silicon or ceramic sensitive elements to convert static pressure into electrical signals.

The basic working principle of the submersible level Transducer is hydrostatic level measurement.

In the liquid medium, the pressure generated at a certain depth is generated by the weight of the medium above the measurement point. It is proportional to the density of the medium and the local gravitational acceleration.

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 level Transducer is actually pressure. It can be known from the calibration unit mH2O of the submersible level Transducer.

The actual liquid level must be obtained through conversion after knowing the two parameters of density and acceleration of gravity. After temperature compensation and linear correction, it is converted into a 4-20mADC standard current signal output.

Such conversion is usually performed by secondary instruments or PLC in the industrial field.

Water level transducers are also called Water Level Sensors, or water level transmitters. Water level transducers are used to monitor water usage and quality. The water level signal is output through 4-20mA and other signals, which is convenient for people to monitor the water level.

There are many types of water level transducers. Common ones are input type, ultrasonic, radar and so on.

Sino-Inst offer a wide range of solutions with various pressure ranges, cable lengths and output options.

For remote monitoring and recording of water level data in groundwater pumping and sludge testing, stormwater flood analysis and runoff, and surface water irrigation canals, streams and river measurements.

If you need non-contact measurements. Then you can choose to use ultrasonic level meter. Ultrasonic technology is not only used to measure level, but also can be used to measure depth.

Submersible Level Transducers are widely used in water level measurement. Including fire pools, water supply tanks, wastewater treatment, deep wells, etc. Especially deep wells.

Mainly because of the following advantages of Submersible Level Transducers:

  1. Low cost. Submersible Level Transducers are relatively the lowest cost liquid level meter;
  2. High precision and long-term stability. Because of the use of ceramic capacitors and diffused silicon measurement units;
  3. It is extremely convenient to install and use. Submersible Level Transducers are directly put into the measured liquid, and the sensor part can be fixed by flange or bracket;
  4. Long service life. High-precision measurement can be performed from water, oil to paste with high viscosity. It is not affected by the foaming, deposition and electrical characteristics of the measured medium. Wide range of temperature compensation.
  5. It can meet various working conditions. Can change the material, measure sewage, corrosive liquid. Can meet IP68. Can meet explosion-proof etc.

A submersible water level sensor works by measuring the pressure of the water column above it. The sensor is placed inside a water tank or well and connected to a data logger or monitoring device. As the water level changes, the pressure at the sensor changes, allowing it to accurately measure the height of the water column. This information is then transmitted to a monitoring device which can display the water level in real-time.

The best sensor for measuring water level will depend on the specific application and the environment in which it will be used. For example, submersible pressure sensors are ideal for measuring the water level in a tank or well, while ultrasonic sensors are better suited for surface water level applications. It’s important to consider factors such as accuracy, reliability, and cost when choosing the right water level sensor for your needs.

A hydrostatic water level sensor works by measuring the pressure of a fluid column, typically water, relative to atmospheric pressure. The sensor is placed inside a tank or well and connected to a monitoring device. As the water level changes, the pressure at the sensor changes, allowing it to accurately measure the height of the water column. The monitoring device then displays the water level in real-time.

There are several types of sensors that can be used to measure water level in a tank, including submersible pressure sensors, ultrasonic sensors, and float sensors. Each type of sensor has its own unique advantages and disadvantages, so it’s important to consider the specific needs of your application when choosing the right sensor. For example, submersible pressure sensors are often the preferred choice for measuring water level in a tank because of their accuracy and reliability.

The Submersible Level Transducer is based on the principle that the measured static pressure of a liquid is proportional to the height of that liquid. It is made of advanced isolated diffused silicon sensitive element or ceramic capacitive pressure sensitive sensor. Convert static pressure to electrical signal. After temperature compensation and linear correction. A pressure sensor for measuring liquid level that is converted into a standard electrical signal (generally 4-20mA/1-5VDC).

Submersible Level Transducer selects high-quality diffused silicon quartz thin-film sensor as the measuring element. Using a stainless steel housing, the top of the sensor diaphragm is protected with a through-hole stainless steel cap. And make the liquid contact the diaphragm smoothly. The measured liquid level is not affected by changes in the external atmospheric pressure. Accurate measurement and good long-term stability. It can be directly put into water, oil and other liquids for long-term use.

Submersible Level Transducer is widely used in water level measurement. It can also measure corrosive liquids such as hydrochloric acid, sulfuric acid, nitric acid, hydrofluoric acid, sodium hydroxide, hydrogen peroxide, or chemical and electroplating wastewater.
