Continuous Level Instrumentation

Continuous level measurement is used for solid and liquid level monitoring in silos, storage tanks, vessels and other open or closed storage systems.  These measurements are taken by continuous level sensors, which are manufactured in various styles to measure and monitor the levels within an entire system.

They are different than point level sensors because they provide solid and liquid level measurement at all points instead of only sending an alert when the media reaches a specific level.  Continuous level sensors are used for corrosive and non-corrosive substances and by a range of industries including oil and gas, agriculture, food and beverage, wastewater treatment, concrete/aggregate and several others.

Continuous Level Measurement and Monitoring

For applications requiring precise readings, Branom Instrument Co. offers a huge selection of continuous level sensors and monitoring instrumentation. Whether you’re managing the contents of a 55-gallon drum or a massive grain silo, we have the ultrasonic level sensors, radar level sensors, magnetostrictive devices, capacitance level measurement, and other equipment you need for exact measurements.  We offer the following:

Capacitance Level Sensors

Capacitance level measurement is used for continuous level measurement of liquids and semi-solid media. Capacitance level sensors feature a stainless-steel probe encased in a low-dielectric insulative shell. The probe is immersed in the liquid being measured and takes measurements by generating a radio frequency signal and then calculating changes in current. These readings are then converted into an analog signal that is transmitted to an alarm or other notification system.

Hydrostatic (Pressure) Transmitters Level Sensors

Hydrostatic pressure transmitters are completely submerged in a fluid to provide continuous level measurement of hydrostatic pressure and are commonly used in tanks, vessels, reservoirs, and natural bodies of water. As the depth of a fluid increases, the amount of downward force or pressure caused by gravity also increases. Hydrostatic level sensors provide fluid level readings by measuring the pressure between the ground level or bottom of a vessel, where the level sensor is submerged, and the surface level of the fluid.

Guided Wave Radar Level Sensors

Guided wave radar level sensors that use microwave technology to provide continuous level measurement of liquids and dry bulk media. These continuous level sensors feature a probe that is immersed in the media and takes measurements by sending high frequency waves down the probe until they meet the surface of the media. Once the high frequency waves reach the surface of the media, they are transmitted back up the probe to the sensor.

Since guided wave radar level sensors have no moving parts, they require minimal maintenance. These continuous level sensors also continue to provide accurate readings regardless of changes in pressure or temperature and are not affected by dust or viscosity.  

Magnetostrictive Level Sensors

Magnetostrictive level sensors provide continuous liquid level measurement and are constructed of a sensor housing attached to a metal probe with a magnetic float. The probe is inserted into the liquid in a vertical position and the float rises and falls as the levels change.

To measure fluid levels, an electric current pulse flows through the rod at regular intervals and reacts with the magnetic field created by the float. This reaction creates a torsional stress that sends a vibration up the rod that is then read by the sensor housing and transferred to a meter. The amount of time it takes for the vibration to reach the sensing unit is what indicates the float’s position on the probe.

Non-Contacting Radar Level Sensors

Non-contacting radar level transmitters feature an emitter that transmits high frequency waves through the air and towards the surface of the media. The high frequency waves then bounce off the surface of the media and back to the sensor to provide a measurement. Non-contacting radar level sensors can be used with liquid or solid media and since no contact is involved, are suitable for a range of applications involving food, beverages, oil, gas, chemicals and more.

Ultrasonic Level Sensors

Ultrasonic level sensors are positioned at the top of a tank and use ultrasonic pulses to create a signal.  The signals transmitted from the sensor reflect off the surface of the media and back to the sensor. The time it takes for the signal to return to the sensor is used to measure the distance between the ultrasonic level sensor and the surface of the media. Since these continuous level sensors never make contact with the media, they are suitable for use with corrosive nongaseous substances and hazardous chemicals.
