Types of Level Sensor
|
There are many physical and application variables that affect the selection of the optimal level monitoring method for industrial and commercial processes. The selection criteria include the physical: phase (liquid, solid or slurry), temperature, pressure or vacuum, chemistry, dielectric constant of medium, density (specific gravity) of medium, agitation (action), acoustical or electrical noise, vibration, mechanical shock, tank or bin size and shape. Also important are the application constraints: price, accuracy, appearance, response rate, ease of calibration or programming, physical size and mounting of the instrument, monitoring or control of continuous or discrete (point) levels. Level sensor has many types: *RF Admittance level sensor, which can detect point and continuous level for solids. *Magnetic Level Indicator can detect point level for liquids. *Ultrasonic Level Sensor is the Sensor for both point level detection and continuous monitoring. |
