ELECTROMAGNETIC FLOWMETER ELECTROMAGNETIC FLOWMETER 1

EFS800 - CFT180/RFT200 ELECTROMAGNETIC FLOWMETER Accurate, Reliable and Stable Flow Measurement. Measuring Principle The measuring principle of the electromagnetic flowmeter (Magmeter) is based upon the Faraday s Law of electromagnetic induction; whereby a voltage is induced by an electrical conductor passing through a magnetic field. The following equation is applicable to the induced voltage: U = kbvd where U k B V D Induced voltage Instrument constant Magnetic field strength Velocity of the conductor Conductor width In electromagnetic flowmeter, the medium acts as the electrical conductor when flowing through the meter tube, the induced voltage is proportional to the average flow velocity (the faster the flow rate, the higher the voltage). The induced voltage is picked up by a pair of electrodes (mounted in the meter tube) and transmitted to a flow transmitter to produce various standardized output signals. Using the pipe cross-sectional area, the flow volume is calculated by the transmitter. Applications isolv electromagnetic flowmeter can be used for precise flow measurement of all electrically conductive liquids - sludges, slurries, sewage, milk, water. The only pre-requisite being that the minimum conductivity of the medium is greater than 5μS/cm. Temperature, viscosity, density has no influence on the measurement. With isolated inert linings and electrodes, Flow measurement of very corrosive liquids (eg: acids, accaustics and corrosive chemicals) is not an issue. isolv electromagnetic flowmeter has many applications across many industries environment.

Grounding the Primary Flow Sensor Primary flow sensor in metal pipe 1) Measuring ground 2) Grounding wire 10mm 2 Cu (AWG 7) Primary flow sensor in plastic pipe or in metal pipe with insulating coating / lining / painting 1) Measuring ground 2) Grounding wire 10mm 2 Cu (AWG 7) 3) Grounding rings 5 Primary flow sensor in pipe runs with cathodic protection Primary flow sensor must be electrically isolated from the pipe. Protective rings for good grounding are compulsory. 1) Measuring ground 2) Grounding wire 10mm 2 Cu (AWG 7) 3) Grounding rings 4) Screw bolts (insulated) 5) Connecting wire 10mm 2 Cu (AWG 7) Installation Location and position as required, but electrode axis ( x...x ) must be approximately horizontal. Pipe must be completely filled at all times. Flow direction - Avoid top / bottom Ensure there is sufficient clearance for installation and maintenance work. Straight inlet run minimum of 5xDN and outlet 2xDN (DN= meter size) measured from the electrode axis. Support the pipeline on both sides of the flowmeter to minimise vibrations. Do not install flowmeter in vicinity of strong electromagnetic fields. Example: High-tension electrical cables Install protective rings for plastic pipes and internally coated metal pipelines for proper grounding. ELECTROMAGNETIC FLOWMETER 7

Some Typical Installations A & B - Preferred locations. (Pipe is fully filled!) C - Highest point of pipe run (Air bubbles accumulate in measuring tube causing incorrect or unstable measurements) D - Top/bottom flow direction to drain does not create a fully filled pipe condition causing unstable or inaccurate reading. Install in slightly ascending pipe section. If not possible, ensure adequate velocity to prevent air, gas or vapour from concentrating in the flow sensor. Install flow sensor in lower section of pipe. Install air valve downstream of flowmeter. Negative pressure (Vacuum) may damage the liner. Always install control and shutoff valves downstream of flowmeter to avoid flow profile distortion or possible negative pressure (Vacuum) Never install flow sensor on pump suction side (Vacuum!). May cause damage to the liner. Install flowmeter in bypass for heavily contaminated fluids. 2 A) Flowmeter B) Flushing and cleaning without interrupting system operation ELECTROMAGNETIC FLOWMETER 8
