Level limit switches of the SONOCONTROL series, in connection with ultrasonic sensors, are used for universal level limit detection in systems carrying liquid. The measuring system features a number of benefits: · The ultrasonic sensors are attached to the outside of the vessel; they are not in exposed to the liquid in the tank. · As measurement is made from outside, the liquid can be pressurized or be chemically toxic or aggressive. This has no effect on the measured data. · The measuring method is particularly suitable for application in the pharmaceutical and the food industries. · Foam on the liquid does not affect the accuracy of the measurement. · The system can easily be fitted to existing vessels without expensive testing if the vessel is a pressure vessel. The SONOCONTROL 20 is of universal application: · Level monitoring of tanks · Dry-running protection of pumps · Detection of gas bubbles in liquids · Level monitoring in pressure bottles · Dosing control · Inspection of pipeline pig systems · Ice level alarm on ice silos. The SONOCONTROL 20 level limit switch has many functions and supports the use of complex instrumentation systems: · A microcontroller ensures high measuring accuracy and data integrity. · The parameters required for installation can comfortably be input via buttons. The parameter inputs are not lost if the power supply is interrupted. · A serial port supports data exchange with a computer. All parameters can be set and measured values obtained at this port. The port has bus capacity and supports the parallel connection of up to 32 series SONOCONTROL 20 / SONOMETER 30 units. · The SONOCONTROL 20 is available as a single-channel or two-channel version. The second channel permits the independent monitoring of a second limit level or measurement by ultrasonic transmission (see chapter 3.3.3). · As a rule, the SONOCONTROL 20 is located in the control room. The distance to the sensor on the vessel can be up to 300 meters.
