Measuring Principle 1:100 Measuring Span t 99: < 1 sec. Temperature of The Medium -22 to 356 ºF Operating Pressure -14.5 to +435.1 psig Ambient Temperature -4 to +158 ºF Direct Current (DC) Voltage 18 to 36 V Power 5 W Outputs As standard: RS 485 (Modbus-RTU), 4…20 mA, pulse Optional Output Ethernet Interface M-Bus Power over Ethernet (PoE) Benefits Benefits at a glance:New: Unique sensitivity in the lower measuring range: Measures from as little as 6.56 f/s and thus covers the complete operating range of variable speed drive (VSD) compressorsParticularly suitable for extremely high flow ratesFlow, total consumption, temperature and pressureMeasurement at high temperatures, max. temperature 356 ºFCan be used in pipes from 3/4" to 24"Installation via 1/2" ball valve under pressure Field of Application Measurement immediately downstream of the compressorMeasurement at high temperatures Typical Applications Measurement of the capacity of compressorsCompressed air auditsEfficiency measurement of compressed air systems Installation Requirements After functioning water separatorIn horizontal lines (recommended) or in risers Additional Information The integrated, precise differential pressure sensor measures the differential pressure/ dynamic pressure at the sensor tip. The pressure depends on the respective gas velocity.The flow is therefore easy to determine by means of the pipe diameter.The additional measurement of temperature and absolute pressure and calculation of the relevant density means that measuring can be carried out for various gases, a wide variety of temperatures and pressures.
