flow meteringfrom ifm.
Volumetric flow sensor efector mid. High-precisionmeasurement, display and signalling of liquid media.
For industrialapplications
Coolant monitoring Cooling water monitoring
Ideal in widelybranched coolingsystems, e.g. weld -ing lines. Thevolumetric flowsensor efector middetects very smalldeviations fromthe specified volu-metric flow quan-tity, for examplefor leaks, andmonitors at thesame time thetemperature ofthe cooling water.This guaranteesprocess safety andquality.
Decentraliseddetection andmonitoring ofliquid media.
The diagnosticfunctionality ofefector mid, e.g.analogue outputs,binary limit values,consumed quanti-ties during thespecified period ortemperature mo n -itoring in themedium, enablesthe reliable opera-tion of cooling cir -cuits and systems.Due to the contin -uous monitoringthe sensor can beperfectly integrat -ed into the condi-

tion-based main-tenance concepts.This enhances thereliability of theplant; uptime isincreased. Expen -sive consequentialdamage resultingfrom lack of cool -ant is prevented.By integration intoa real-time-main-tenance conceptmaintenance canbe implementedat the right time,in the right place,using the rightmaterial and oper -ators.
The magnetic-inductive volumet -ric flow sensor issuitable for moni-toring conductivemedia. The mediahave a differentelectrical conduc -tivity. efector midmeasures liquidmedia from aconductivity of> 20 μS/cm.

Measuring lengthand electronics areintegrated into arobust and com-pact housing. Sootherwise usualinlet and outletpipe lengths canbe reduced to aminimum. Pressureloss is negligible.
Compact, informativeand easy to install.
Four-digit alpha-numeric displayfor information onsite: current volu-metric flow, accu-mulated totalquantity andmedium tempera-ture. l/min or m3/hcan be selected asthe unit of mea -surement. TwoLEDs indicate theswitch points.Mounting viaR 1/2 or R 3/4adapter ensureseasy installation inthe pipe.
Cooling process optimisation Water supply documentation
efector mid – thereliable and low-cost solution formonitoring theexact supply andconsumption ofliquids in industri-al processes. Dueto the measuringrange of 0 to25 l/min and anaccuracy of ± 2 %of the measuredvalue the unit canbe used in a widerange of applica-tions. Volumetricflow in the oppo -site direction isalso indicated.

Ensuring product qualityand plant up-time.
Volumetric flow sensorefector mid:
Simultaneous monitoringof volumetric flow quantityand temperature of con-ductive liquids.
Functionality and precisionat the right price.
Local indication of thecurrent volumetric flowquantity, total quantity andtemperature.
For external evaluation:Switching, pulse and ana -logue outputs for signaland control tasks.
Less cost:Setting and monitoring ofcooling circuits for optimumperformance.
More safety:Immediate detection ofeven very small leaks.
High transparency:Counting and allocation ofconsumed quantities.
Exactly right:Exact determination ofliquid quantities.
Magnetic-inductiveflow metering.
converted in theevaluation electro-nics. As the pipecross-section isdefined, thevolu met ric flowquantity can bedeterminedexactly.
No moving com-ponents are used,therefore thesystem works relia-bly, wear andmaintenance free.
The volumetricflow sensor isbased on Faraday’sprinciple of induc-tion. The conduc-tive mediumflowing through apipe in a magneticfield generates avoltage which isproportional tothe flow velocityor volumetric flowquantity. This vol-tage is tapped viaelectrodes and
