Thermal Flow Switch – Vetrix TFS-FRC Series

Features

  • The unique tapered probe design prevents the entanglement of the winding in the media.
  • Full waterproof case body design, unique waterproof adjustment knob, can be adjusted without disassembling the sealing screw, it is more reliable.
  • Applicable to a wide range of pipe diameters, free to adjust the setpoint, optional anti-corrosion type, withstand voltage up to 100Bar.
  • The indicator light directly shows the flow, optional relay, analog output or analog, switch output integrated output.
  • Monitor the liquid flow in the pipeline in real-time, no moving parts, maintenance-free, easy to install.
  • Adopt 6 The LED displays the fluid flow rate status in real-time: media flow, reduced/ increased flow rate; media presence/absence; media flow/stationary; monitoring fluid flow rate within the pipe, shut-off monitoring or preventing pump idling.

TFS-FRC series electronic thermal flow switch, based on the thermal principle, enclosed in a closed probe contains two resistors, one of which is heated as the sense resistor and the other is not heated as the base quasi-resistance when the medium flows, the heat on the heating resistor is taken away, and the resistance value is changed.

The unique tapered probe design prevents the entanglement of the winding in the media. Full waterproof case body design, unique waterproof adjustment knob, can be adjusted without disassembling the sealing screw, it is more reliable. Applicable to a wide range of pipe diameters, free to adjust the setpoint, optional anti-corrosion type, withstand voltage up to 100Bar, the indicator light directly shows the flow, optional relay, analog output or analog, switch output integrated output. BL-FRC series electronic thermal flow switch can monitor the liquid flow in the pipeline in real-time, no moving parts, maintenance-free, easy to install, one model is used for a variety of pipe diameter requirements, provide switching output, and adopt 6 The LED display the fluid flow rate status in real-time, enabling the following monitoring functions: media flow, reduced/ increased flow rate; media presence/absence; media flow/stationary; monitoring fluid flow rate within the pipe, shut-off monitoring or preventing pump idling.

Applications

It is widely used in petrochemical, electric power, metallurgy, steel mills, paper making, food processing, water treatment, battery factories, and other industries. Gas-liquid dual-purpose, for pneumatic and hydraulic systems, for shut-off monitoring of circulating water, cutting fluids and lubricants, and idling protection of pumps.

Dimension

Electrical Wiring

Note:
According to the wiring diagram, the wiring is correctly connected. When the probe touches the medium, when the probe touches the medium, the indicator light is observed. If the red light is on, it can be adjusted counterclockwise. Only the timing adjustment can be made. If the green light is on, it can only be adjusted counterclockwise. Cannot adjust clockwise.

Cautions For Installation

When installed vertically, the flow should be flows from bottom to top in the pipe section.
