cynergy Ultrasonic Flow Meter UF25B This innovative design provides a high accuracy, non-invasive, flow measurement device at a fraction of the cost of other current non-invasive systems. The unique measurement technique automatically compensates for viscosity and temperature variations. The measurement of flow is by ultrasonic transit time in-line cell. The flow path is designed to minimise pressure drop and, having no moving parts within, will not clog or jam. The sensor also allows contaminants to pass through without affecting its performance. The sensor is supplied with pulse and analogue outputs, which are selectable by connection wires.. • Non-invasive sensor technology • Fully electronic, no moving parts • Automatic viscosity and temperature compensation • Pulse or analogue output selectable • Low pressure drop • LED indication of no liquid & of flow rate Technical Specifications Max. flow L/min (Q4) Transitional flow L/min (Q2) Min. flow L/min (Q1) Output selectable 25 0.5 0.2 Pulse Analogue Performance Accuracy for flow rates between Q2 and Q4 Accuracy for flow rates between Q1 and Q2 Resolution better than Reverse flow Response time 3% of reading 5% of reading 0.001L/min 0-25L/min Better than 0.1s Interface Connection 8 wires (RED supply +ve, BLACK ground, Blue NPN output, Yellow Data in, White PNP output, Orange Voltage output, Brown Current output, Green Ground connected internally to black) Supply 7.5 - 26VDC (input current <10mA @ 9VDC) Output selectable 1000 pulses/L 0-5Vdc 4-20mA Operation Principle Temp. range (fluid) Continuous fluid sound Ultrasonic transit time in-line flow cell -10°C to 85°C Maintains performance regardless of fluid type, temperature or viscosity for speed measurement fluids with sound speeds 1250 - 1750 m/s Physical characteristics Flow tube material Flow tube internal diameter Connection thread Internal bore of connection Suitable Pushfit adaptor (to fit 1/2” OD Tube) Maximum pressure Case material Case integrity Connection Environmental protection Glass filled plastic, Grivory HTV-4FWA Black 9225 (FDA and EU approved for ffodstuffs) 10mm 3/8” BSP 10mm John Guest Speedfit PI451613S 10 bar ABS black, Polylac PA-757 Ultrasonically welded, not liquid proof 8 core, PVC sheathed, 100cm long standard Internal electronics conformally coated.
