E SERIESE ELECTROMAGNETIC FLOWMETER (SEPARATE TYPE) DATA SHEET FMF1,2/FMH The electromagnetic flowmeter is an instrument to measure the volumetric flow rate of liquid simply by applying a magnetic field from the outside utilizing the fact that an electric conductor which crosses a magnetic field at a certain velocity causes voltage to be induced in proportion to the velocity, which is known as Faraday’s law. This flowmeter is designed with the latest electronics technology, realizing a compact and light-weight structure and measurement with high accuracy. FEATURES 1. High accuracy When conductivity is above 5 µS/cm, flow rate of liquid can be measured regardless of density and viscosity. The measurement accuracy is as high as 0.6% of rate. 2. Free power supply The flowmeter operates on power supply 100 to 230V AC, 50/60Hz. 3. Grounding electrode Use of the grounding electrode of Hasteroy C in the flowmeter allows installation without an earth ring. • Mounting method : Mounted via flange insertion type on opposite (with Guide rings) ··· 3A to 100A Note 1) Guide ring : A ring-shaped guide used for centering the sensor when a wafer type is mounted on the piping. Note 2) Flange with meter size 3A or 6A can be used for 15A. 4. Change of settings. The setting of various parameters can be changed from the outside of the case cover. Application of the supplied magnetic stick to the outside glass surface enables the setting to change without opening the case cover. 5. Stable measurement of flow rate A digital filter for pulsating or noisy flow signal, flow rate output low cut, and damping function allows flow rate measurement to be stabilized. 6. Self-diagnosis function Since self-diagnosis function is provided for empty detection, trouble, and maloperation, the flowmeter can be used with safety. 7. Simultaneous display of instantaneous flow and total flow 2-stage display with LCD backlight which is visible in the dark.

When installing, be sure to observe the following points. q The measuring pipe should always fill with fluid which flows in the piping. Fluid may not fill up the pipe. Air are apt to from. Fluid may not fill up the pipe. Good Good Pump Example of mounting posture w The signal electrode should be at a level with the ground. And also signal electrode and ground electrode should always keep contact with fluid. If the signal electrode or the ground electrode is upper position against the fluid, correct measurements cannot be expected due to air bubbles on the fluid. Signal electrode Ground electrode Ground Ground < Good > < Good > Ground electrode Signal electrode Ground electrode Signal electrode Ground Ground < No good > < No good > Position of electrode How to connect the grounding cable contacting with measuring liquid. Since the electromagnetic flowmeter is provided with a grounding electrode, flow rate of liquid can be measured without an earth ring. However, if stray potential exists in a pipeline, the potential in the pipeline may fluctuate. In this case, the earth ring (option) of the same material as signal electrode and ground electrode should be mounted on the upstream and downstream sides of the flowmeter to connect to the grounding terminal. For liquid that contains attachments or deposits, take the liquid contacting ground from the optional earth rings and metallic pipe (without lining).
