Stork Analogue Submersible Water Level Sensor, 0-5MWG, 4-20mA, 2-Wire, G1/4″
The SLS range of underwater level sensors has been developed using a durable stainless steel housing that encloses an isolated diaphragm silicon piezo-resistive sensing element. This design allows the submersible level transmitter sensors to withstand depths of up to 100 meters when fully submerged in liquids, ensuring continuous operation.
These water level sensors come with two options for output. The first option is a raw millivolt output, which is ideal for applications requiring low power consumption. Alternatively, the sensors can be equipped with an internal microprocessor that provides an amplified output, such as 4-20mA, 0-10V, or 0.5 to 4.5V ratiometric signals.
The integrated 16-bit microprocessor on board the sensors enables advanced features like high-level linearization, temperature compensation, and calibration. These capabilities ensure that the sensors deliver exceptional accuracy, stability, and repeatability, making them suitable for demanding applications such as environmental monitoring, flood defence systems, and measuring water levels in rivers, reservoirs, and boreholes.

What is a Submersible Level Transmitter?
A submersible level transmitter is a device used to measure and transmit the level of liquids, such as water, when submerged. It is designed to be placed underwater and provides accurate readings of the liquid level. The transmitter sends this information to other devices or systems for monitoring or control purposes.How Does a Submersible Level Transmitter Work?
A submersible level transmitter works by utilising a sensing element, typically a diaphragm with a piezo-resistive material. When the transmitter is submerged in a liquid, the pressure exerted by the liquid on the diaphragm changes. This pressure change is converted into an electrical signal by the sensing element. The transmitter then processes and transmits this signal to indicate the level of the liquid.What is a Submersible Pressure Transmitter for Level Measurement?
A submersible pressure transmitter for level measurement is a device specifically designed to measure the level of liquids by sensing the pressure exerted by the liquid column. It is designed to be submerged in the liquid and converts the hydrostatic pressure into an electrical signal, which can be used to determine the liquid level accurately.What are Water Level Sensors?
Water level sensors are devices used to measure and monitor the level of water in various applications. They are designed to detect and provide information about the height or depth of water in tanks, wells, rivers, reservoirs, and other water bodies. These sensors can use different technologies, such as pressure sensing, ultrasonic waves, or capacitive measurements, to determine the water level and provide corresponding output signals for further processing or control purposes.Related products
