Several types of sensors are offered with M-910, M-920 and M-930 Compact and remote version for different applications. While com- pact version is delivered with protection IP67, remote version sensor DIN or ANSI flanges according to standards EN1092-1 or ANSI B16.5 are delivered as standard. For special purpose different type of Sanitary flanges and PTFE liner according to DIN 11851 standard with typical application in food industry. Hard rubber or PTFE liner is manufactured. Maximal available dia- meter for hard rubber is 800 mm, for PTFE liner up to 300 mm. CrNi steel, Hastelloy or...

Accessories & Options Earthing rings Principle of operation of electromagnetic flowmeter requires the working liquid to be conductive and grounded. To meet this condition in systems with plastic pipes Earthing rings can be ordered. The rings are inserted between sensor flange and flange of the pipe and electrically connected to ground. Extra cable for remote version Remote version is delivered with 6m long cable. The cables is removable both on sensor and transmitter side. Set of cables consist of two separated cables, one is applied for coil excitation, the second for electrodes sensing....

Flowrate versus sensor diameter The choice of flowrate for an electromagnetic flowmeter depends on the diameter of the sensor. The higher pipe diameter, the higher flowrate can be measured. A determining parameter for flowrates is maximum velocity of the liquid. Maximum velocity is the speed, where the flow of liquid inside pipe is still laminar. In M910 it is limited to 10m/s (with 125% overload). Speed over 10 m/s is usually too high for industrial applications. Such diameter of pipe is usually selected, where expected flowrate is between Q5% and Q50%. In the table bellow applicable...
