Introduction

The liquid level transmitter is an essential device used in various industries to accurately measure and monitor liquid levels. One such type of transmitter is the capillary tube liquid level transmitter, also known as the capillary type level transmitter.

Functionality and Principle

The capillary tube liquid level transmitter operates on the principle of hydrostatic pressure. It consists of a sensing element (transducer), a capillary tube, and a reference chamber. The transducer measures the liquid pressure exerted on it, which is directly proportional to the liquid level. The capillary tube connects the transducer to the reference chamber, allowing for the transmission of the liquid pressure to the transducer. By measuring this pressure, the transmitter provides an accurate indication of the liquid level in the tank or container.

Advantages and Applications

The capillary tube liquid level transmitter offers several advantages over other types of level transmitters. Firstly, its compact design allows for easy installation in tight spaces. Additionally, the use of a capillary tube improves its accuracy, especially in applications where the liquid level changes frequently or rapidly. This type of transmitter is widely used in industries like oil and gas, chemical processing, water treatment, and food and beverage.

Maintenance and Troubleshooting

To ensure the proper functioning of the capillary tube liquid level transmitter, regular maintenance is crucial. This includes cleaning the transducer, checking for any leaks or damages in the capillary tube, and calibrating the transmitter periodically. In case of any issues, common troubleshooting steps include inspecting the wiring connections, verifying power supply, and assessing the condition of the reference chamber. Proper maintenance and troubleshooting help prolong the lifespan of the transmitter and ensure accurate measurements.
