Submersible Level Transmitters

filter_list

Submersible level transmitters are important devices used in the field of level monitoring for reliable level measurement. They work on the principle of hydrostatic pressure. The pressure exerted by a column of liquid is measured by these transmitters to determine the level of the liquid in a tank, well, or bore hole.

The submersible level transmitter consists of a sensing element and a transducer. The sensing element, typically a diaphragm, is affected by the pressure of the liquid. The transducer then converts this pressure into an electrical signal which can be interpreted into the liquid level.

Hydrostatic level measurement is a precise and reliable method that can handle harsh applications and deliver excellent linearity, low hysteresis, and long-term stability. This type of transmitter can handle a wide range of conditions and materials, which makes it versatile for different uses.

More Information about Submersible Level Transmitters

A submersible level transmitter is designed to be lowered into the tank or well with a cable. For smaller tanks or bore holes, transmitters with a small diameter are available. Some models are also designed to be lowered into groundwater and other subterranean liquid sources.

These devices are vital for a variety of industries such as wastewater treatment, oil and gas, and even for measuring groundwater levels for environmental monitoring. The transmitters can be installed in the liquid environment and provide continuous, accurate measurements. This can help customers monitor their systems and processes to maintain optimal operation.

When the level of liquid in the tank changes, the hydrostatic pressure on the sensor also changes. The transmitter measures these changes and transmits the information as an electrical signal which can be used to monitor and control the level of liquid. In this way, submersible level transmitters provide continuous and accurate monitoring of liquid levels.

 

Transmitters vs Transducers

Some of the most common types of transmitters and transducers can be found on pressure instruments. Examples of these include: drop-in well pressure devices and devices that measure the pressure in a pipe or gas chamber. Transmitters and transducers can also be found on flow and speed measurement devices. 

What is the difference between transmitters and transducers? 

The main difference is the way they send data to the monitoring device, like a PLC. In terms of measurement, the transmitter will reference a measuring unit by sending a milliamp signal (such as 4-20 mA). A transducer will reference a measuring unit by sending a voltage signal, typically in volts or millivolts.  

Why have the two different types of transmission methods? 

The method will depend on the application. If the electrical connection in the application travels a short distance, a pressure transducer is the better choice. Pressure transducers are smaller with fewer active electronic components that can be upset by electromagnetic interference. Also, the voltage signals transmitted over longer distances are subject to voltage drop and signal corruption. A transmitter is better for transmitting signals over a long distance.
