Ultrasonic Level Monitor

Ultrasonic Level Monitor: Non-Contact Level Measurement for Tanks, Sumps and Channels

Knowing how much liquid is in a tank or sump helps you prevent overflows, avoid pumps running dry, control processes and keep reliable records. The Ultrasonic Level Monitor from EOEnergy Pvt. Ltd. measures liquid level without touching the liquid. It is mounted above the surface and uses sound waves to read the level, which makes it a practical choice for water, wastewater and many industrial applications.

 

What Is an Ultrasonic Level Monitor?

An ultrasonic level monitor is an instrument that measures the level of a liquid in a tank, well, sump or open channel. A sensor sends out a short ultrasonic pulse towards the surface of the liquid. The pulse bounces back, and the instrument measures how long this takes. Since the speed of sound is known, the time is converted into the distance between the sensor and the surface, and from this the level, or the quantity remaining, is calculated and displayed.

 

How Does It Work?

The monitor has a sensor, which is fitted at the top of the tank, and a transmitter or display unit, which processes the signal and shows the reading. The sensor sends and receives the pulses many times a minute, so the reading keeps updating as the level changes. Depending on the model, the reading can be shown as level, distance or volume, and the data can be sent to a PLC, SCADA system or data logger. Alarm and relay outputs can also be used to start or stop pumps or to warn of high and low levels.

 

Key Benefits

Non-contact measurement: Because the sensor does not touch the liquid, it is not affected by corrosion, deposits or sticky materials in the way that probes can be.

No moving parts: There is nothing inside the tank to wear out, jam or break, which supports long and dependable operation.

Easy installation: The sensor is fitted at the top of the tank or channel, so there is usually no need to empty the tank or stop the process.

Suitable for many liquids: It can be used for water, wastewater, effluent and many chemical and process liquids, depending on the model.

Useful outputs: Level readings can be viewed on the display and sent to control systems, with alarm options for high and low levels.

Low maintenance: Routine upkeep is minimal, which helps keep running costs low.

 

Where Can It Be Used?

Ultrasonic level monitors are used in water storage tanks and overhead reservoirs, sewage and effluent treatment plants, sumps and wet wells, open channel and drain monitoring, cooling water systems, chemical and process tanks, and irrigation and storage reservoirs. In plants that must monitor and report effluent, level measurement also supports flow monitoring and record keeping.

 

Things to Keep in Mind

Ultrasonic level measurement works very well in many situations, but the site conditions matter. Heavy foam on the liquid surface, thick vapour or steam, strong dust, and obstructions such as pipes or ladders in the path of the sound beam can affect the reading. The sensor should also be fitted at the correct height and away from the tank wall and the inlet stream. For these reasons, the right model and mounting should be chosen for your application. Our team can help you decide.

 

Choosing the Right Level Monitor

To recommend a suitable model, please keep the following details ready: the liquid being measured, tank shape and height, the minimum and maximum level range, whether the tank is open or closed, and the presence of foam, vapour or dust. Also tell us what output you need, such as a display, analog signal, relay or digital communication.

Frequently Asked Questions

1. How does an ultrasonic level monitor work?
It sends an ultrasonic pulse towards the liquid surface and measures the time the echo takes to return. This time is converted into distance, and then into level or volume.

2. Does the sensor touch the liquid?
No. It is mounted above the liquid and measures without contact, so it is not affected by corrosion or deposits on a probe.

3. Can it be used in any tank?
It suits many tanks, sumps and channels, but heavy foam, thick vapour or steam, strong dust and obstructions in the sound path can affect readings. Please share your site conditions so we can recommend a suitable model.

4. Can it be connected to a PLC or SCADA system?
Depending on the model, output options are available to send level data to a PLC, SCADA or data logger, along with relay outputs for alarms or pump control. Please tell us your requirement.

5. What information do I need to select the right model?
Please share the liquid type, tank shape and height, level range, whether the tank is open or closed, and any foam, vapour or dust at the site.
