Remote version operating temperature: RUBBER -10 ÷ +80☌ PTFE -40 ÷ +150☌Ĭompact version operating temperature: RUBBER -10 ÷ +80☌ PTFE -40 ÷ +100☌ SS316L – Hastelloy C – Titanium – Tantalum – Platinum RPmag is able to process signals from fluids with flow rates of up to 10 m/s in both directions (bidirectional meter). The converter can be supplied with the most common communication systems such as MODBUS RTU. Various materials for lining are available, as well as electrodes made of Hastelloy C, tantalum and titanium. The special magnetic coil design results in high precision without having to reduce the. This allows optimal pump performance without energy loss in the system. It complies to 2014/32/EU directive and to OIML R 49-1/2/3, EN 14154-1/2/3, ISO 4064-1/2/5 standards. The electromagnetic flow meters PF75 are highly precise and equipped with a continuous measuring tube without constriction or fittings, which prevents pressure loss in the system. Transit- time meter – 0.RPmagM with MID certification is suitable for all industrial processes where fiscal and custody transfers are required. Installation can be considerable, Relatively maintenance-freeĭoppler shift meter – 1% of reading to 2 % of full scale Modern installation effort, minimal maintenance Most suitable for non-intrusive measurement The construction of Electromagnetic Flow Meter we need to consider the material selection for Electrode & liningĮlectrode Material – Ti (Titanium),Ta (Tantalum), Hb, Hc as they are resistive to corrosion. Selection of material for Electromagnetic Flowmeter The usage of the meter is restricted to fluids that are electrically conductive, and it is appropriate for installations that can only withstand a slight pressure drop.A fluid’s conductivity will rise when salts are added to it.Heavy coatings (insulating & shorting) can result in measurement errors.Limitations of Electromagnetic Flow Meter There is no problem with measurements of laminar and turbulent flows because the working principle is independent of fluid density and viscosity, responding simply to average velocity.Suitability for working with corrosive liquids.The wattage usage of the instrument is under 5VA.Measurement accuracy is unaffected by changes in fluid density, viscosity, temperature, pressure, and conductivity it can also detect positive and negative two-directional flow rate, which has made it possible to measure flow rate accurately.Low installation demand since only the liner and electrode are in direct contact with the measured medium, which allows for good non-corrodible and wearability to measure a variety of acid and alkali chemical solutions.It has a great ability to save energy, making it particularly well suited for measuring liquid-solid two-phase flows such sewage, slurry, ore pulp, water-coal pulp, paper pulp, and so on.The factors that determine fluid in flow meter areĬharacteristics of Electromagnetic Flowmeter The accuracy of the flow measurement can be affected by factors such as the conductivity of the liquid, the temperature of the liquid, and the presence of air bubbles in the liquid.ĭetermining Factors of Electromagnetic Flowmeter It’s important to follow the manufacturer’s instructions for installation, calibration, and maintenance of the flowmeter. To stop the flow of liquid, close the valve on the pipe.Monitor the flow rate on the display or recording device.Calibrate the flowmeter by adjusting the display or recording device to match the known flow rate of the liquid. ![]() Open the valve on the pipe to start the flow of liquid.Connect the flowmeter to a power source and a flow rate display or recording device.Install the flowmeter in a horizontal pipe that is at least 5 pipe diameters long and has a straight run of at least 3 pipe diameters on either side of the flowmeter.How to use Electromagnetic Flowmeters?īelow mentioned are some of the basic steps for using an electromagnetic flowmeter The induced voltage is observed by electrode and connected to external signal condition circuits which processes the output. A voltage that is proportionate to the fluid velocity is induced as the fluid moves in relation to the field. ![]()
