Sapcon’s Rate of Flow level sensor is RISC Processor based continuous level indicator (level transmitter). The series of this sensor utilizes the principle of capacitance for level measurement. Apart from level indication, the built-in three point electronic level limit switch offers the switching functions for alarm annunciation and/or control application at the set point levels. The set points are independent of each other and are continuously configurable over the entire range.
The sensor is suitable for measuring the level of conductive or non conductive liquids, slurries and powdered or fine grained solids homogeneous composition having a stable dielectric constant.
In an application, the measuring electrode (sense probe) is provided with a stilling tube which forms a capacitor. The amount of capacitance of this capacitor is governed by the level of water between the two electrodes (sense probe & stilling tube). ROF measures the Change of Capacitance to measure the Change of Level of the water. This level is then converted to the Rate of Flow, depending on the weir type selected or K,n parameter entered for the equation for calculating Flow Rate.
