2021 Hot Sale 4-20mA Customized Durable Submersible Liquid Level Transmitter Water Tank Level Probe Sensor

Product Overview

The Submersible Liquid Level Transmitter is designed for continuous level measurement of water and other compatible liquids in tanks, reservoirs, wells, and industrial containers. It converts hydrostatic pressure into a standard 4-20mA output signal, enabling reliable remote monitoring and integration with control systems such as PLCs and SCADA.

Built with a durable submerged probe structure, this sensor is suitable for long-term installation in demanding environments where stable performance and corrosion resistance are required.

Key Features

• 4-20mA analog output for industrial compatibility
• Submersible probe design for direct liquid measurement
• Stable long-term operation in water tanks and wells
• Suitable for continuous level monitoring applications
• Designed for durability in humid and submerged environments

Applications

This liquid level transmitter is widely used in water supply systems, wastewater treatment, irrigation reservoirs, industrial storage tanks, and environmental monitoring systems. It is especially suitable for applications requiring continuous level feedback and automated control.

Working Principle

The sensor operates based on hydrostatic pressure measurement. As the liquid level changes, the pressure exerted on the submerged probe varies proportionally. This pressure is converted into an electrical signal and transmitted as a standard 4-20mA output for further processing and display.

Installation Notes

Install the probe vertically into the liquid medium, ensuring it is fully submerged and stable. Avoid direct impact from inflow streams or turbulence to maintain measurement accuracy and long-term stability. Proper cable sealing and strain relief are recommended for outdoor or submerged installations.

FAQ

What media can this level transmitter measure?

It is primarily designed for water and similar non-corrosive or mildly corrosive liquids. Compatibility depends on the sensor housing material and installation conditions.

Can it be used in deep wells or underground tanks?

Yes, the submersible design allows it to be used in deep wells, underground tanks, and reservoirs, provided the pressure range matches the application depth.

What output signal does it provide?

It outputs a standard 4-20mA analog signal, which is widely supported by industrial controllers and monitoring systems.

Does it require frequent maintenance?

Under normal operating conditions, the transmitter requires minimal maintenance. Periodic inspection is recommended for optimal long-term performance.
