Submersible Hydrostatic Level Transmitter

A. Product Overview

The Hydrostatic Level Transmitter is designed for accurate and stable liquid level measurement in tanks, wells, sumps and reservoirs. It is suitable for non-corrosive liquids compatible with stainless steel and is commonly used where continuous level monitoring is required.

This transmitter comes with a submersible probe, durable cable and stainless steel body. The sensor uses a high precision diffused silicon core and digital circuit design to provide reliable measurement. Its 316L stainless steel isolation diaphragm makes it suitable for different liquid media, while the IP68 protection level helps the transmitter perform in submerged and harsh working conditions.

The transmitter supports multiple output options such as 4 to 20 mA, 0 to 10 V, 0 to 5 V and RS-485. It operates on 12 to 36 VDC power supply, with 24 VDC as the typical supply voltage. The product is available with an adjustable measuring range of 0 to 2 meters and can be customized as per application requirement.

B. Working Principle

The Hydrostatic Level Transmitter works on the principle of hydrostatic pressure. When the probe is submerged in liquid, the liquid column above the sensor creates pressure on the diaphragm. This pressure increases as the liquid level rises and decreases as the liquid level falls.

The internal sensing element converts this pressure into an electrical signal. This signal is then processed by the transmitter electronics and sent to a controller, PLC, indicator, data logger or monitoring system through standard outputs such as 4 to 20 mA, voltage output or RS-485.

In simple terms, the transmitter measures the pressure created by the liquid height and converts it into a level reading. This allows continuous and real-time monitoring of liquid level inside tanks and open containers.

C. Why It Is Used

The Hydrostatic Level Transmitter is used because it provides continuous, stable and accurate liquid level measurement without requiring moving parts. This makes it a dependable choice for water tanks, sewage systems, industrial tanks and process applications.

It is especially useful in applications where float switches or mechanical level devices may not provide enough accuracy or continuous output. The transmitter gives a proportional signal, which helps users monitor exact liquid level instead of only high level or low level point detection.

It is also preferred because of its compact submersible design, IP68 protection, stainless steel body, 316L diaphragm, reverse connection protection for current output and stable performance. The polyurethane cable and laser precision welding improve durability and reduce leakage risk.
