Working Principle‌

Fluid-Driven Mechanism‌:

Liquid flow drives the measurement gears based on the gear motor principle.

Signal Generation‌:

One signal is emitted per gear tooth rotation, corresponding to a fixed geometric volume.

Dual non-contact sensors sample gear movement for bidirectional flow detection.

Bearing System‌:

Low-friction ball bearings ensure contactless operation.

Pressure-resistant non-magnetic separator isolates the sensor compartment.

Signal Processing‌:

A preamplifier converts raw signals to square waves.

Two-channel sampling enhances resolution and flow direction identification.
