fluid technology solutions

RS flow meters measure the flow rate based on the screw pump principle. A pair of rotors fitted precisely into the housing constitutes the measuring element. An integrated gear and non-contact signal pick-up system detects the rotations of the measuring element and converts them to digital pulses. Together with the housing walls, the rotor edges form closed measuring chambers in which the fluid is transported from the inlet to the outlet side. The fluid volume put through within one main rotor rotation is the rotation volume, which is divided by the sensing gear and digitised, processed and output...

SENSOR ELECTRONICS DESCRIPTION A special sensor system detects any movement of the pair of rotors or of the liquid column. For this purpose, a precision gear connected to a shaft of the rotor pair is scanned by a special magnetoresistive sensor. The scanning sensor includes two GMR-bridges (sin/cos) and is housed in a removable stainless steel cartridge case together with a signal conditioning and amplifier unit. The downstream electronics unit features a high-resolution sin/cos-interpolator, which is adjustable with ten different resolution factors. Furthermore, a programmable signal filter...

SENSOR MODULE PULSE FILTERING PRINCIPLE Oscillations in fluid systems manifest themselves through constant forward and backward movements of the liquid column, which is also detected by the rotor sensors and converted into proportional electronic pulses or edge sequences. These generated pulses can be incorrectly interpreted by the downstream evaluating unit or controller, which can be very distracting for the respective operating process. The signal filtering function of the internal electronics continuously offsets these generated edges during the rapid forward and backward movements of the...
