• Direct compressed air measurement with simultaneous display of three measured values thanks to standard TFT display
• Best system integration thanks to two analog outputs: 4 … 20 mA
• Highest measurement accuracy and integrated measuring tube avoid measurement errors
• Simple and cost-effective installation

In industrial companies, compressed air is an important energy source with high consumption costs. With Testo flow transmitters you get a very accurate measurement of compressed air consumption, allowing you to identify the potential for energy savings and lower costs. The flow transmitters can also be used for a targeted implementation of an environmental management system – e.g. according to ISO 50001 or ISO 14001.

Another application is leakage monitoring in compressed air systems. The flow transmitter can also be used to perform a peak load analysis to determine if compressed air is being generated with sufficient capacity. The newly developed “all-in-one sensor” records not only compressed air consumption and temperature, but also pressure, eliminating the need for a separate pressure measurement.

The flow transmitters of the testo 645X family use the calorimetric measurement principle, which makes additional pressure and temperature measurements unnecessary. In addition, there is no wear and tear on moving parts.

testo 6454 flow meter for compressed air

Inlägget testo 6454 – flow transmitter 2,5 … 700 m³/h dök först upp på Nordtec.

The testo 6456 flow transmitter measures the standard air flow in compressed air according to the calorimetric principle, which means that the measurement method is independent of the process pressure and does not cause any permanent pressure loss.

Flexible: Suitable for large pipe diameters DN 65 – 250
Clear overview: Direct compressed air measurement with simultaneous display of three measured values thanks to the standard TFT display.
Best system integration: Dual analog output, or pulse and analog output.
Optional: With built-in pressure measurement (with output option F02)
Four measurement parameters in one instrument: flow rate, totalizer, temperature and pressure (with output option F02).

The testo 6457 measures the standard air flow in the compressed air according to the calorimetric principle, which means that the measurement method is independent of the process pressure and does not cause any permanent pressure loss.

The testo 6457 flow transmitter has a patented quick coupling, which allows the sensor to be removed under pressure. This is a great advantage, especially in the case of larger nominal widths, as these often involve main lines that do not allow pressure relief for maintenance purposes.

Flexible: Suitable for large pipe diameters DN 65 – 250
Clear overview: Direct compressed air measurement with simultaneous display of three measured values thanks to the standard TFT display.
Quick release: the sensor can be removed under pressure
Three measurement parameters in one instrument: flow rate, totalizer and temperature.

testo 6457 flow transmitter

Inlägget testo 6457 – flow transmitter 8 … 27 450 m³/h dök först upp på Nordtec.

• Can be installed under pressure
• Measures flow velocity (m/s) in the measuring range 0…80 m/s or 160 m/s, consumption measurement in Nm³ and median temperature in °C.
• The backstop and ball valve ensure quick and safe installation and de-installation of the compressed air sensor on site. This means that several sites can be covered by one sensor.
• Maximum flexibility thanks to different signal outputs:
  – Analog output 4 to 20 mA (4-wire)
  – Pulse output
  – 2 binary outputs (parameterizable: consumption- or volume flow-dependent, opening, closing, hysteresis, window)

The probe is optimized for easy, safe and quick installation and can be used for measurements on different pipe diameters. An optimal drilling clamp enables precise positioning of the sensor without the need for welding.

The respective supply line may remain under pressure when installing this drill clamp or during maintenance / replacement of the sensor (normal operating conditions). A ball valve allows the compressed air line to be closed securely and airtight when removing the sensor and when reinstalling it.
