Insertion Mass flow meter DN50 - DN700

HLX776

The HLX776 flow meter is based on the thermal mass flow measurement and is ideal for measuring the flow of compressed air and gases in pipes from DN50 to DN300. With the HLX776, the consumption of compressed air, nitrogen, CO2 or other non-corrosive and non-flammable gases can be measured up to a pressure of 16 bar, for example.

Patented non-return protection for secure mounting

The HLX776 flow meter set new standards in terms of safety and easy assembly. The patented non-return protection combines three functions in one device:

• Non-return protection
  The sensor can only be pushed in one direction during installation. The sensor cannot return at all, even if it is released.
• Seal
  By means of an encapsulated O-ring, no compressed air can escape under pressure during assembly.
• Precise positioning
  The precise positioning with respect to immersion depth and orientation is easy to perform, guaranteeing accurate measurement results.

An optional ½“ ball valve enables the installation and removal of the sensor without interrupting the flow in the compressed air line.
The high measurement accuracy of 2.5% from reading results from the application-oriented factory adjustments, which are undertaken at 9 bar pressure.
Two signal outputs are available to output the measured values. Depending on the application, these can be configured as an analogue output (current or voltage), switching output or pulse output for consumption measuring.
