产品介绍
FMG71B 电磁流量计
Electromagnetic Low Flow Meter
The FMG70B Series from OMEGA is a trio of extremely compact, low cost, inductive magnetic flow sensors. Changes of temperature, density, viscosity, concentration or electrical conductivity (minimum conductivity of 50 µs/cm) of the fluid do not affect the output signal. FMG70B series can be used in areas where flow sensors with moving parts e. g. paddle wheel sensors, cannot be applied due to contamination/particulate in the media. The sensor is intended for continuously measuring of flow rates or for dosing/batching of electrically conductive liquids. Specifications Model FMG71B FMG72B FMG73B Flow Range 0.5 to 30 l/min 1 to 60 l/min 5 to 250 l/min Accuracy ±(1.5% of reading + 0.3% of range) Signal Output Starts from Approx. 0.4 l/min Approx. 0.9 l/min Approx. 4 l/min Repeatability 1% Liquid Type and Minimum Conductivity Water and other conductive liquids with minimum conductivity of 50 µS/cm Liquid Temperature 5 to 90 °C Ambient Temperature 5 to 70 °C (with media up to 70 °C) Maximum Pressure 16 bar (PN 16) Diameter DN 7 DN 10 DN 20 Process Connection G1/2A or 1/2" NPT G1/2A or 1/2" NPT G1A or 1" NPT Flow Indication Green LED, blinking proportional to flow rate Output Signals Frequency Output Pulse Rate 1000 pulses/litre 500 pulses/litre 100 pulses/litre Resolution 1.0 ml/pulse 2.0 ml/pulse 10 ml/pulse Signal Shape Square wave NPN, internal pull-up resistor 2 kΩ.
