Working principle One helicoidal rotor turns freely inside a cylindrical tube.  Chemical and petrochemical industry The working liquid pushes the rotor blades, making them turn at a flow speed which is proportional to the flow rate.  Tank filling and batching applications A pick-up coil mounted externally receives the propeller turns and generates an electrical signal which, once treated by the different electronic converters, provides:  Burners, measurement of fuel consumption  Measurement of steam condensates in boilers - Flow rate indication Technical data - Total or partial...

Turbine flowmeters Series TM Mounting It is essential to avoid cavitations inside the turbine flowmeter. In order to do this, on the outlet of the flowmeter the pressure must be at least twice the pressure drop of the flowmeter, plus 1.25 times the vapour pressure of the liquid. For both horizontal or vertical pipes and installation in all flow directions (horizontal pipe is recommended for DN125 and DN150). A straight pipe run without any disturbing element (elbows, valves, filters, etc) of 10 x DN before and 5 x DN after the turbine flowmeter is required. The upstream distance can be...

Flow ranges Flow scales Max. intermittent pulses / litre ∆P mbar The TM turbine flowmeters are calibrated with water (density 1 kg/l and viscosity 1 mPa·s). It is recommended that minimum flow rate is at least 10% of the flow scale in order to obtain the highest accuracy. The measurement errors can be corrected in the different associated electronic converters by means of the adjustment of the k factor (pulses / volume unit), obtaining a maximum accuracy. A change in viscosity can modify the k factor. The measurement error due to these changes in viscosity is approximately indicated in the...
