Working Principle?

The device operates on a thermal measurement principle. Its sealed probe contains two resistors:

Heated resistor?: Serves as the sensing element.

Reference resistor?: Maintains ambient temperature.

When fluid flows, heat dissipation from the heated resistor alters its resistance value. The differential resistance between the two resistors determines the flow velocity.

Key Features?

Maintenance-free?: No moving parts.

Universal installation?: Single model accommodates multiple pipe diameters.

Low pressure loss?.

Integrated functions?:

Color LCD displays flow trend and switch status.

Built-in temperature measurement with alarm and remote monitoring capabilities.

Applications?

Media compatibility?: Liquids (water, oil), gases, and gas-liquid mixtures.

Typical uses?:

Low-flow alarms.

Pneumatic/hydraulic systems.

Coolant/lubricant flow monitoring.

Pump dry-run protection.
