Flow sensors www.ifm.com/mid Compact and low-cost monitoring of conductive liquids. Magnetic-inductive flow metering from ifm.
For industrial applications Volumetric flow sensor efector mid. High-precision measurement, display and signalling of liquid media. Decentralised detection and monitoring of liquid media. Ideal in widely branched cooling systems, e.g. weld - ing lines. The volumetric flow sensor efector mid detects very small deviations from the specified volumetric flow quantity, for example for leaks, and monitors at the same time the temperature of the cooling water. This guarantees process safety and quality. Coolant monitoring Cooling water monitoring Condition-based maintenance. Monitoring of conductive liquids. The diagnostic functionality of efector mid, e.g. analogue outputs, binary limit values, consumed quantities during the specified period or temperature mo n - itoring in the medium, enables the reliable operation of cooling cir - cuits and systems. Due to the contin - uous monitoring the sensor can be perfectly integrat - ed into the condi- tion-based maintenance concepts. This enhances the reliability of the plant; uptime is increased. Expen - sive consequential damage resulting from lack of cool - ant is prevented. By integration into a real-time-maintenance concept maintenance can be implemented at the right time, in the right place, using the right material and oper - ators. The magneticinductive volumet - ric flow sensor is suitable for monitoring conductive media. The media have a different electrical conduc - tivity. efector mid measures liquid media from a conductivity of > 20 μs/cm. industrial water electrical conductivity sea water (salt) water glycol mixtures water-based coolants drinking water
efector mid the reliable and lowcost solution for monitoring the exact supply and consumption of liquids in industrial processes. Due to the measuring range of 0 to 25 l/min and an accuracy of ± 2 % of the measured value the unit can be used in a wide range of applications. Volumetric flow in the oppo - site direction is also indicated. Photo reference Induction hardening: R. Rieker GmbH, Leingarten Wafer production: centrotherm thermal solutions GmbH+Co KG, Blaubeuren Cooling process optimisation Water supply documentation alphanumeric display switch point indication programming buttons Compact, informative and easy to install. Measuring length and electronics are integrated into a robust and compact housing. So otherwise usual inlet and outlet pipe lengths can be reduced to a minimum. Pressure loss is negligible. Four-digit alphanumeric display for information on site: current volumetric flow, accumulated total quantity and medium temperature. l/min or m 3 /h can be selected as the unit of mea - surement. Two LEDs indicate the switch points. Mounting via R 1/2 or R 3/4 adapter ensures easy installation in the pipe.

Ensuring product quality and plant up-time. Volumetric flow sensor efector mid: Simultaneous monitoring of volumetric flow quantity and temperature of conductive liquids. Functionality and precision at the right price. Local indication of the current volumetric flow quantity, total quantity and temperature. For external evaluation: Switching, pulse and ana - logue outputs for signal and control tasks. Less cost: Setting and monitoring of cooling circuits for optimum performance. More safety: Immediate detection of even very small leaks. High transparency: Counting and allocation of consumed quantities. Exactly right: Exact determination of liquid quantities. V M E Magnetic-inductive flow metering. The volumetric flow sensor is based on Faraday s principle of induction. The conductive medium flowing through a pipe in a magnetic field generates a voltage which is proportional to the flow velocity or volumetric flow quantity. This voltage is tapped via electrodes and M = magnet E = electrodes V = flow velocity M converted in the evaluation electronics. As the pipe cross-section is defined, the volu met ric flow quantity can be determined exactly. No moving components are used, therefore the system works reliably, wear and maintenance free.
