Kofloc Products

Kofloc gas mass flowmeters and back pressure valves support gas measurement and pressure regulation. Explore the flowmeter range and 6800 valve, with selection based on gas composition, flow range, operating pressure and connection requirements.

Kofloc Gas Mass Flowmeters & Back Pressure Valves

SL Measurement supplies Kofloc instruments for gas flow measurement and upstream pressure regulation. This range includes gas mass flowmeters and the Kofloc 6800 back pressure valve.

Begin with the task: measuring gas consumption or flow rate, maintaining pressure in a vessel, or selecting a replacement for an existing instrument. The gas, operating conditions and required connections help determine the appropriate configuration.


Gas Mass Flowmeters

Kofloc mass flowmeters measure gas flow in a fixed installation. When selecting a meter, specify the gas or mixture, the normal working flow and the maximum required flow. Confirm the calibration basis and flow units so the instrument matches the process requirement.

Electrical connections, power supply and communication options depend on the selected model. For a replacement, provide the complete model code and details of the existing signal or control system.

If your application requires automatic flow adjustment, include this in your enquiry so the required control function can be checked alongside the measurement specification.


Kofloc 6800 Back Pressure Valve

The Kofloc 6800 regulates pressure on the upstream side of the valve. Listed applications include tank pressure control and mixed-gas systems where maintaining pressure before the valve is part of the process.

Its compact construction supports panel mounting. Selection should account for the required upstream pressure, downstream conditions, gas flow and connection size.


Choosing a Kofloc Instrument

A clear description of the operating conditions helps narrow the selection. Please include:

  • Gas: Gas name or mixture composition, including any compatibility requirements.
  • Flow: Minimum, normal and maximum flow, with the units and reference conditions used.
  • Pressure: Available inlet pressure, expected outlet pressure and any required pressure setting.
  • Installation: Operating temperature, tubing size, fitting type and mounting space.
  • Electrical requirements: Available power supply, output signal and communication interface where applicable.
  • Function: Flow measurement, automatic flow control or upstream pressure regulation.

Replacing an Existing Kofloc Meter or Valve?

Send a clear photograph of the nameplate together with the full model code. For a flowmeter, include the gas and calibrated range. For a back pressure valve, include the working pressure and connection details.

Photographs of the fittings and electrical connector can also help identify the existing configuration and the details that need matching.

The KOFLOC 6800 series regulates pressure on the upstream side of a gas system by releasing gas when pressure exceeds the selected setting. Its compact design suits panel-mounted equipment and tank pressure control.

  • Pressure settings: 0.01–0.3 or 0.01–0.6 MPa(G), depending on model.
  • Maximum exhaust flow: 0.8, 1 or 10 L/min, depending on model and operating conditions.
  • Connections: Rc 1/4 or Rc 1/8.
  • Selection: Four versions with material options to suit the gas.

KOFLOC thermal mass flow meters and controllers measure or regulate gas flow in laboratory equipment, gas supply systems and industrial processes. Select a mass flow meter for measurement, or a mass flow controller for automatic regulation to a setpoint.

  • Gas selection: Air, nitrogen and other compatible gases, with the appropriate calibration.
  • Model options: Standard meters, display-equipped instruments and metal-sealed configurations.
  • Integration: Analogue signals and digital communication depend on the selected model.
  • Existing 8500/D8500 users: The discontinued series has a manufacturer-designated alternative in the 8700 range, subject to configuration checks.
