The Submersible Level Transmitter is the most commonly used tank level indicator. There are stainless steel probes that are placed at the bottom of tanks, wells, or other liquid containers. Output 4-20mA signal. For liquid level measurement and control.
The difference between the SMT3151TR Hydrostatic Submersible Level Transmitter and other submersible level transmitters is that it is a straight rod insertion type.

Applications of Submersible Level Transmitter
Sino-Inst’s Hydrostatic Level Transmitter is used in various industrial and municipal environments. Especially in water supply and wastewater treatment plants. Mainly used for water level measurement of urban water supply, oil tanks, petrochemical and other open tanks.
Hydrostatic Level Transmitter measures the hydrostatic pressure of a liquid medium. Liquid level information is transmitted through electrical signals. The signal changes linearly and proportionally. To measure the hydrostatic pressure above the sensor.
If your measurement range is greater than 5 meters, please refer to Submersible Pressure Transducer.
- Level measurement in rivers and lakes
- Level measurement in vessel and storage systems
- Control of sewage lift and pumping stations
- Monitoring of sewage, settling and stormwater retention basins
If you are measuring the fuel tank level, you can choose a magnetostrictive liquid level sensor with higher accuracy and longer service life.

Installation of Submersible Level Transmitter
The rod type static pressure liquid level transmitter has two standard installation methods of G11 / 2 thread and flange.
For the transmitter that is directly installed with G11 / 2 thread, a G11 / 2 round nut is provided at the time of delivery. Generally, there are two ways for installation.
- The installation position has G11 / 2 thread. The liquid level transmitter can be screwed in directly. The attached round nut can be used or screwed on to prevent loosening.
- There is no G11 / 2 thread in the installation position. Can use the existing Φ50 ~ Φ60 light hole, or install a bracket with Φ50 ~ Φ60 hole. Install the liquid level transmitter, and screw on the round nut to fix it.
The standard installation dimensions of flanges are in accordance with DN50, GB9119.6-88
If there are other flange mounting holes in the installation location, please indicate the flange size or the corresponding specifications and standard numbers when ordering, in order to meet the installation requirements.
Of course, we can also directly measure the liquid level with a pressure transmitter. For example, install a Hydrostatic pressure transmitter directly at the bottom of the tank. The installation is shown on the right.

What is hydrostatic level transmitter?
Hydrostatic level transmitter is actually a type of pressure transmitter. Hydrostatic level transmitter is the application of pressure transmitter to liquid level measurement. The submersible Hydostatic pressure level transmitter is based on the principle that the measured liquid static pressure is proportional to the height of the liquid. Piezoresistive effect using diffused silicon or ceramic sensitive elements. Convert static pressure into electrical signal. After temperature compensation and linear correction. Convert to 4-20mADC standard current signal output. In order to achieve liquid level measurement.

Submersible level transmitter working principle
The basic working principle of Hydrostatic Level Sensor is static pressure level measurement.
In liquid, the pressure generated at a certain depth is generated by the weight of the medium itself above the measurement point. It is proportional to the density of the medium and the local acceleration of gravity.
The formula P = ρgh reflects the proportional relationship between them.
Where P = pressure, ρ = medium density, g = gravity acceleration, h = depth of measurement point.
Therefore, the physical quantity measured by the input liquid level gauge is actually pressure. It can be understood by the calibration unit mH2O of the input level gauge. The actual liquid level must be obtained by conversion after knowing the two parameters of density and gravity acceleration. In the industrial field, such conversion is usually performed by a secondary instrument or PLC.
The Hydrostatic Level Sensor mainly measures corrosive liquids such as hydrochloric acid, hydrogen peroxide, etc. Or chemical and electroplating wastewater. Mainly used in measuring corrosive media. It has the advantages of strong corrosion resistance and stable performance.
