Ultrasonic flow sensor SEMIFLOW CO.66 PI Ex1

volumefor liquidsrugged

The new SEMIFLOW Ex1 Set opens a new product category of intrinsically safe ultrasonic flow sensors with control gear for non-contact liquid flow measurement on small and midsize rigid plastic tubes to ensure safe operation in hazardous areas. SEMIFLOW CO.66 PI Ex1 sensors are protected against explosion hazard by gases, vapors, and liquids according to the gas group IIB. The device protection level (EPL) is "Gb" for the use in Zone 1 according to ATEX/IECEx. The Barrier Box ST Ex1 is used to limit the energy supplied to the SEMIFLOW flow sensors to avoid ignition according to IEC 60079-11 (ATEX/IECEx). The device provides all necessary power and data interfaces to the operators outside the Ex-Zone and allows the intrinsically safe SEMIFLOW to be used in hazardous areas with possible fire or explosion risks due to explosive gas atmospheres (Zone 1, Group IIB). •Highly precise and contact-free measurement •8 sensor sizes (¼", 3/8", ½", (¾"), 1", 1 ¼“, 40A, 50A OD) for a wide range of tube sizes •Plastic housing (PVCC) and plastic connector (PA) •Screwed lid and flexible inlay for an optimal coupling between tube and transducer •No external electronics for a compact design and simple handling •Customer calibration for different flow rates
