Submersible Level Transmitters

Submersible Level Transmitters are known by several names including Hydrostatic Level Sensor, Submersible Level Sensor, Submersible Pressure Transmitter or Submersible Level Probe. All are designed to accurately continuously measure the depth or level of liquid. The concept is very simple: Water has a specific gravity (SG) of 1 which equates to 100 mBar of pressure per metre of liquid level. The pressure is measured by the level transmitter which directly equates to the liquid level. A typical example would be 10 metres of liquid level equates to 1 bar of pressure. Other liquids such as Diesel have a different specific gravity of roughly 0.85 which means 10 metre level would be 0.85 bar pressure. There are many different applications, hence different designs that should be considered when selecting the right level transmitter. The main criteria is the sensor diameter, the depth to be measured, the output required such as 4-20 mA and the environment it will be fitted. Our selection includes slimline borehole transmitters, Hazardous area ATEX approved, Digital output SDI-12 & RS-485 Modbus level transmitter and high volume, low cost IoT solutions.

Frequently Asked Questions About Submersible Level Transmitter Pressure Sensors

A submersible level transmitter is a device used to measure the level of a liquid or fluid in a tank or vessel. It is designed to be submerged in the fluid, allowing it to provide accurate and reliable level measurements.

Submersible level transmitters typically use a pressure sensor or a strain gauge to measure the pressure exerted by the liquid or fluid. The pressure reading is then converted into a corresponding level measurement using a calibration or conversion formula.

The main components of a submersible level transmitter include a pressure sensor or strain gauge, a housing or enclosure to protect the electronics, a cable for power and signal transmission, and various electrical connections for integration with control systems.

Submersible level transmitters can measure various types of fluids, including water, oil, chemicals, wastewater, and many others. The specific type of transmitter and its materials of construction may vary depending on the compatibility requirements for the fluid being measured.

When selecting a submersible level transmitter, you should consider factors such as the type of fluid being measured, the operating temperature and pressure range, the required accuracy and resolution, the tank or vessel configuration, and any specific environmental or regulatory requirements.
