Continuous level measurement and level detection in liquids and solids.
What is level measurement ?
The level measurement is about the level of liquids, solids, and powders that exhibit an upper free surface, inside a container or in its natural form. It is detected by level measurement sensors which are divided into two main types;
Point level measurement sensors are used to mark a single discrete liquid height present level condition. Generally, this type of sensor functions as a high alarm, signaling either an overfill or a low-level condition.
Integrated into process control in many industries, level sensors are used to indicate the level in liquids, solids or liquefied gases. They are often measured in tanks, silos or mobile containers.
Continuous level sensors can provide level monitoring of an entire system. They measure fluid level within a range, producing an analog output that directly correlates to the level in the container. additional, to create a level management system, the output signal is linked to a process control loop and to a visual indicator.
There are a large number of measurement principles for level measurement, radiometric level measurement, radar level measurement, ultrasonic level measurement, interface measurement, density measurement, and level detection. We assist you from planning to maintenance of your measuring point, including commissioning.

Level measurement Liquid Level Controllers
SOR Liquid level controllers monitor liquid levels in vessels and send a pneumatic signal to a local control system or directly to a control valve. Liquid level controllers are ideal for interface measurements, making them an excellent choice for measuring the level on gas separators and scrubbers. The reliability of the level measurement instrument design makes it well suited for liquid level applications in natural gas production, compression, and processing.
Level measurement: level Indicators
Level measurement: RF Level Transmitters
SOR RF level switches are used to measure the level of a liquid or bulk solid material (as well as slurries) within a specified space. Level measurement instruments are designed to measure point level readings. Point level switches provide the output when a specific level measurement is reached.
Level measurement: OEM Flow Switches
Vertically mounted, vane-operated flow switches are suitable for plant and OEM applications where open or closed contacts are required to signal flow or no flow conditions. The vane extension arm moves a magnet that actuates (de-actuates) a hermetically sealed reed switch, which is encapsulated in the body of the unit, out of the fluid path. Decreasing the flow below the calibration point causes the reed switch to de-actuate.

Nuclear level measurement technology has been applied effectively to measure liquids and solids for more than 30 years. the basic method of measuring the nuclear level is the sending of radiation through the liquid and the intensity of the transferred radiation is measured using a detector.
