Paddle flow meter PWE series

volumefor liquidsplastic

Supports up to 23 Engineering Units (including one User Defined) Two programmable Totalizers (main and pilot) indicate total liquid volume Programmable High and low Flow Alarm limits with preset delay interval Programmable High and low Temperature Alarm limits with preset delay interval (optional) Two sets of user programmable optically isolated outputs Flow Pulse output (3.3Vdc CIMOS) Extensive Self Diagnostic with LCD (optional) indication Local key pad and 2x16 characters LCD display with adjustable back light (optional) Enclosure weather tight to IP65 standards Description Liquid flowing through the unit causes the paddlewheel to spin. As the magnets embedded in the paddle wheel spin past the sensor, electrical pulses are produced in which the frequency is proportional to the flow rate. The number of pulses per desired time interval and the K-factor (number of pulses/Gallon) make it is possible to calculate the flow rate and volume passing through the unit. On board CPU and signal conditioner circuitry perform accurate flow and total computation, digital communication and provide analog 0-5 Vdc or 4-20 mA output signals. Non-volatile memory stores all hardware specific and ser programmable variables, including flow linearization table. The flow rate can be displayed in 23 different volumetric or ass flow engineering units. Flow meter parameters and functions can be programmed locally via key pad and LCD* or remotely via the RS-232/RS-485 interface.
