Electro-Mechanical Flow Transmitter HFT 2100 for Oils and Viscous Fluids

The HFT 2100 series of Hydac flow transmitters, based on the variable area float principle, are available through HFT.

This test medium moves a spring-loaded float in the direction of flow, depending on the flow rate, but irrespective of the mounting position.

A Hall sensor, which detects the position of the float, is fitted to the outside of the instrument and is therefore separate from the flow circuit.

In proportion to the deflection of the float, the sensor produces an analogue signal which corresponds to the particular measuring range.

The device is calibrated for vertical installation and for an upwards flow direction. The flow switch is designed to give reliable measurements within its accuracy range, even with changes in viscosity. The viscosity may fluctuate between 30 and 600 cSt.

• Accuracy ≤ ± 10 % FS
• Viscosity compensation from 30 to 600 cSt
• Any mounting position
• High level of functional safety
• High pressure resistance
• Threaded connection

This series of flow transmitters is ideal in the following applications:

• Central lubrication systems
• Oil circuit lubrication systems
• Transformers
• Cooling systems and circuits
• Lubrication circuits
• Hydraulic systems
• Pumps
• Welding machines and laser systems
• Chemical industry
• Research & development
