Helical screw flow meter SVC

for liquids

Two high-precision screw spindles with rolling-element bearings for low friction. The liquid flow makes the spindles rotate (displacement principle) and runs through the device in axial direction. Flow in and out takes place without hardly any deflection, which means the device only loses comparatively little pressure. The measuring principle does not cause any pressure or volume flow pulsation. Because there is no need for settling sections on the inlet and outlet side, machines/plants can be designed to be more compact. All moving parts are lubricated by the measuring medium. The spindle-mounted sensing wheel is scanned by two contact-free sensors by default. The plug is equipped with a pre-amplifier that converts the sensor signal into a square-wave signal which serves as output signal. The dual-channel scanning facilitates a higher measuring resolution and detection of the direction of flow. Alternatively available encoder specifications deliver maximal measurement resolution.
