64.1 Straight pipe sectionsThe point where the FLOMAT sensor will be installed must be a straight pipe section,separated from elements that can disturb the flow profile, such as elbows, diameterchanges, etc. Depending on the element the minimum necessary distances upstream fromthe sensor are shown on the next page (BS 1042-2.2:1983 standard):2 RECEPTIONThe FLOMAT electromagnetic flowmeters with XL1 converter are supplied convenientlypackaged for transportation together with their instruction manual for installation andoperation.All the flowmeters have been verified in our calibration rigs to obtain the gain factor for eachsensor.2.1 UnpackingUnpack the instrument carefully, removing any remains of the packing.2.2 Storage temperatures-20ºC ...... +60ºC3 HANDLINGIt should always be done with care and without knocks.4 INSTALLATIONThis should be made in a straight pipe run that guarantees that the pipe is always completelyfull.Avoid high points of the pipes where air pockets usually form, or pipes with downwardsflow where vacuums can occur.Partially full pipes can involve important reading errors.Flow rate measurement with open discharge makes it necessary to install the flowmeter in apipe section with a siphon which avoids stagnation of air in the sensor.
