Series FLOMAT FLOMAT Electromagnetic Insertion Flowmeter Working pressure manufacturing according to PED 97/23/CE (Lloyd's Register Certificate N° 031) For use in large diameter pipes or open channels as an economical solution for liquid metering. Flow rate for liquids with electrical conductivity better) than 20 uS/cm, for example. - Water treatmernt - Sewage treatment -Acid, neutral or alkaline solutions - Chemical and pharmaceutical products i Suitable for use at low and medium temperatures. The body is constructed in stainless steel EN 1.4404 (SS 316L), on request available in PVDF wetted parts] with electrodes in Hastelloy C, Ziorconium, Titanium. • Readings are independent of density, temperature, • Alternating magnetic field for metering avoids electrolysis I • Absence of obstructing elements gives low pressure I loss and will allow the pass of solids • Can be mounted in any position, provided that the pipe is always full • Good stability with temperature and age • No moving parts provides zero maintenance • Can be installed with short straight pipe sections • Good chemical resistance of construction materials Metering Body Technical Data • Liquid Temperature range: PVDF Head Special Order Field coil current: Liquid Conductivity: Titanium, Zirconium For temperatures above 70°C it may be necessary to I separate the control unit from the metering body, depending on air temperature and ventilation of the | control unit.

Measurement Principle The Flomat electromagnetic insertion flowmeter consists of a sensor which generates a magnetic field in the liquid to be measured. The conductive liquids, as they flow through the magnetic field (5), generate a voltage E6 (6) between the electrodes (3) which is proportional to the liquid velocity (V7). The generated voltage is processed by the microprocessor electronic circuit to give outputs of mA or Hz proportional to the flow rate Q(8). Q8 = K . V7 .

Approximate, depending on the pressure and pipe material C is the necessary distance that the sensor (not the insert) should be inserted into the pipe (fig. 1) FLOMAT 1RS (Remote electronics) FLOMAT 204 mounted with ring FLOMAT 103 mounted with body ring for PVC/PE

Metering body selection The diagram shows the relation between the liquid speed and the flow rate for different body sizes. The metering body diameter should be chosen to obtain a maximum normal working liquid velocity of about 3-4 m/s. Flow rate table l/s 3 Liquid Velocity m/s l/min m /h 160.000 100.000 0,2 ,3 ,4 0,5 ,6 ,7 ,8 ,9 1 2 3 4 5 6 7 8 9 10 20.000 100.000 DN 1400 50.000 DN 1200 10.000 50.000 The minimum working liquid velocity should not be below 0.5 m/s. When the liquid has solids in suspension, it is better to work between 3 and 5 m/s to avoid sedimentation in the pipe and...
