• Installation: Suitable for horizontal, vertical or inclined pipelines, subject to installation requirements.

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.

The RCM Flo-Gage differential pressure flowmeter provides a direct local reading of liquid or gas flow. The mechanical indicator operates without external power and can be specified for water, compatible oils, compressed air and other gases.

• Clear indication: 90 mm analogue dial with a 270° scale.
• Performance: ±3% of full-scale accuracy over a 6:1 measuring range.
• Connections: Series 7000 threaded or Series 8000 wafer construction.
• Options: Material, alarm-switch and transmitter configurations to suit the application.

RCM Flo-Gard II liquid flow switches detect when flow crosses a selected setpoint, providing a contact signal for an alarm or equipment interlock. Applications include cooling-water circuits, chillers and compatible process-liquid systems.

• Switch options: One or two independently adjustable SPDT reed switches.
• Construction: Metal body with material and seal options to suit the liquid.
• Local indication: Optional LEDs show switching status.
• Installation options: General-purpose and intrinsically safe configurations, subject to the required specification.

The Ryutai Kogyo ADF water flowmeter provides a direct visual reading of instantaneous water flow through a transparent acrylic tapered tube. Its compact inline design suits local checks on water supply and circulation pipework.

• Measurement: Variable area flow indication for water.
• Connections: Rc 1/2, Rc 3/4 and Rc 1 threaded options.
• Installation: Vertical mounting with flow from bottom to top.
• Selection: Match the scale, connection size and wetted materials to your operating conditions.

The Ryutai Kogyo EM series metal tube variable area flowmeter measures flow with a magnetically coupled indicator. Select local indication or additional electrical functions to suit your installation.

• Fluid options: Models for clean liquids, gases and steam.
• Body sizes: 15A to 150A, depending on model.
• Functions: Local flow display, analogue output, totalising, pulse output and alarms, depending on configuration.
• Replacement enquiries: EM-series selection is available for older MCF installations, subject to compatibility checks.

The Ryutai Kogyo GTF, ATF, GTV and ATV variable area flowmeters provide direct visual indication of liquid or gas flow. Choose the measuring tube and wetted materials to suit your fluid, pipework and operating conditions.

• GTF: Glass tapered measuring tube.
• ATF: Acrylic tapered measuring tube.
• GTV: Glass tapered tube with PVC construction.
• ATV: Acrylic tapered tube with PVC construction.

Standard installation is vertical with bottom-to-top flow. Measuring scales, connections and alarm options depend on the selected configuration.

The Ryutai Kogyo MCF metal tube flow transmitter provides flow indication and, depending on configuration, an electrical signal for remote monitoring equipment.

• Legacy models: MCF-V, MCF-II and MCF-H are discontinued; the manufacturer identifies the EM series as the replacement range.
• Replacement selection: Match the fluid, measuring range, installation dimensions and required output.
• Existing installations: Provide the complete MCF or E-MCF code and a photograph of the instrument nameplate.

Read and adjust flow at your equipment with Ryutai Kogyo panel flowmeters and purge meters. The GPB, GPC, PGH, GDR and AMF families offer glass or acrylic measuring tubes for direct local indication, with mounting and valve arrangements selected for the installation.

• GPB and GPC: Glass tube panel and laboratory flowmeters.
• PGH: Glass tube purge meter; successor to the older PGF series.
• GDR: Compact glass tube flowmeter with threaded connections.
• AMF: Acrylic tube panel flowmeter.

Select the model using the fluid, flow range, operating pressure, temperature and available panel space.

Tokico electronic positive displacement flowmeters measure oil volume with a local digital display and optional signal outputs. Select the appropriate configuration for diesel, light oil, heavy oil, lubricants or crude palm oil (CPO).

• Measurement: Positive displacement principle with nominal accuracy of ±0.5% within the specified operating conditions.
• Local indication: Electronic display for convenient reading at the meter.
• System connection: Pulse, analogue and alarm functions depend on the selected counter configuration.
• Model selection: Match the flow range, viscosity, temperature, pressure and connection requirements.

For CPO and heated oils: Confirm fluid temperature, viscosity and material compatibility before selecting the meter.

Tokico positive displacement oil flowmeters measure accumulated oil volume through a mechanical counter. Select the appropriate model for diesel, kerosene, heavy oil or other compatible oils.

• Model families: FGB, FRO, FRP and FRA for different flow capacities.
• Accuracy: Typically ±0.5% within the specified operating range.
• Local reading: Mechanical totaliser, with reset-counter options.
• Selection: Match the oil viscosity, temperature, flow rate and connection requirements.

For digital indication and signal-output options, see the Tokico electronic oil flowmeter.
