Flow measurement sensor POA

• Drift-free sensors with abolutely stable zero point • Easy installation durch thanks to perfectly matched mounting accessories • Installation under process conditions possible • The selection of sensor variations ensures the best possible solution for each application • Error-proof connection over long distances thanks to digital signal transmission Specifications: • Measurement principle: - ultrasonic transit time ( level ), - piezo-resistive pressure measurement ( level ), - correlation with digital pattern detection ( flow velocity ) • Measurement frequency: 1 MHz • Protection: IP 68 • Ex - Approval ( optional ): ll 2 G EEx ib llB T4 • Operating pressure: max. 4 bar ( combi sensor with pressure element max. 1 bar ) • Cable length: 10/15/20/30/50/100 m, for sensors without plug ( sensor connection type "K" and "L" ) extendable up to 250 m max. ( 820 ft ); using sensors with integrated pressure measurement cell ( Level measurement, type V1D0 and V1U1 ) requires to use a pressure compensation element after a cable length of 30 m ( 99 ft ). Element may be also used to connect extension. • Type of cable: - Combi sensors with pressure measurement: LiYC11Y 21.5 + 1x2x0.34 + PA 1.5/2.5 - Sensors without pressure measurement: LiYC11Y 2x1.5 + 1x2x0.34 • Outside cable diameter: - Combi sensors with pressure measurement: 9.75 mm +/- 0.25 mm - Sensors without pressure measurement: 8.4 mm +/- 0.25 mm • Medium contacting materials: Polyurethane, stainless steel 1.4571, PPO GF 30
