DIGITAL PADDLE WHEEL FLOW METERS General Description PWE flow meters support various functions including: two independently programmable flow totalizers, user programmable low, high or range flow and temperature alarm, two sets of user programmable optically isolated outputs, self diagnostic alarm, flow pulse output. The flow rate can be displayed in 29 different volumetric or mass flow engineering units. Flow meter parameters and functions can be programmed locally via optional key pad and LCD † or remotely via the RS-232/RS-485 interface. † Optional local 2x16 LCD readout with adjustable...

DIGITAL PADDLE WHEEL FLOW METERS Flow and Temperature† Alarms TABLE 35 - FLOW RATE FOR PWE High and Low flow ALARM limits can be preprogrammed via digital interface or optional LCD/Keypad. ALARM conditions become true when the current reading is equal or higher/lower than corresponding values of high and low alarm levels. Alarm action can be assigned with preset delay interval (0-3600seconds) to activate the optically isolated output (separate for High and Low alarm). Latch Mode control feature allows each optical output to be latched on or follow the corresponding alarm status. FLOW RATE...

DIGITAL PADDLE WHEEL FLOW METERS TABLE 39 - SPECIFICATIONS FOR PWE FLOW MEDIUM: Please note that PWE Flow Meters are designed to work only with liquids. Never try to measure flow rates of dry gas. Performed at standard conditions [14.7 psia (101.4 kPa) and 70 °F (21.1 °C)] unless otherwise requested or stated. Calibrated to 1 cSt (water) meters with display can be used for liquids up to 50 cSt with field calibration (maximum flow range may be affected). ENVIRONMENTAL (PER IEC 664): Installation Level II; Pollution Degree II. FLOW ACCURACY (INCLUDING LINEARITY): LIQUID TEMPERATURE...
