Split-type Ultrasonic Level Transmitter For Level-Level Difference Measure

Ultrasonic level transmitters have no mechanical moving parts, high reliability, easy installation, and non-contact measurement. They are not affected by liquid viscosity and density. Therefore, they are often used for liquid level measurement in medicine tanks, sludge tanks, etc.

Liquid level measurement

Ultrasonic level transmitters are suitable for liquid level measurement after being equipped with sensors. The height of the liquid level is measured by transmitting and receiving ultrasonic signals.

This level transmitter consists of two parts: a sensor placed on the top of the container and a controller connected to the sensor.

Its working principle is based on the characteristics of ultrasonic waves. When ultrasonic waves are emitted from the sensor, they are reflected from the liquid surface and returned to the sensor.

The controller can calculate the height of the liquid level based on the time difference between the emission and reception of ultrasonic waves.

Widely used in the following fields:

Environmental protection field: sewage treatment, sedimentation tank level measurement.

Chemical industry: liquid level monitoring of chemical storage tanks and reactors.

Food and beverage industry: brewing, dairy processing, liquid food storage.

Energy field: liquid and liquid fuel storage in oil, natural gas, and power equipment.

Liquid level difference measurement

When the ultrasonic level meter is equipped with two sensors, it is used to measure the liquid level or material level difference in two different containers.

The most common method is to measure the water level before and after the coarse screen and fine screen at the water inlet of the sewage treatment plant. Calculate the height difference between the water levels. Used to start the reverse drainage and sewage removal machine to remove garbage. When the difference reaches the set value, the screen machine runs to remove the sludge. When the difference drops to the set value, the screen machine stops. There are also installations before and after the gate to measure the water level difference before and after the gate to determine the opening time.

There is another method that does not measure the liquid level difference, but measures the water level height of the two pools, and then outputs 2 channels of 4-20A. This is called a “dual-channel liquid level meter”.

Mainly used in petrochemicals, sewage treatment plants, urban rivers and lakes, sand wells, municipal engineering, water conservancy and hydrology, etc.

Of course, for the sewage treatment industry, we also supply corresponding pressure transmitters and sewage flow meters.
