Description

PWE paddlewheel meter for liquid flow measurement. Design Features oSupports up to 23 Engineering Units (including one User Defined) oTwo programmable Totalizers (main and pilot) indicate total liquid volume oProgrammable High and low Flow Alarm limits with preset delay interval oProgrammable High and low Temperature Alarm limits with preset delay interval (optional) oTwo sets of user programmable optically isolated outputs oUser selectable (via jumpers) analog 0-5 Vdc or 4-20mA flow and temperature (optional) outputs oFlow Pulse output (3.3Vdc CIMOS) oDigital Interface (RS-232 or RS-485) oMulti-Drop Capability of up to 256 units (RS-485 option) oExtensive Self Diagnostic with LCD (optional) indication oLocal key pad and 2x16 characters LCD display with adjustable back light (optional) oEnclosure weather tight to IP65 standards oFree AALBORG configuration and calibration software (RS-232/RS-485) Principles of Operation Liquid flowing through the unit causes the paddle wheel 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.
