Digital compressed air flow meter


Industrial digital compressed air flow meter with electronic digital display to show compressed air instant flow and total flow, it is often with 4-20mA or pulse output, RS485 Modbu RTU or Hart protocol.

With the invention of technology, there have been inventions of useful digital compressed air flow meters. The compressed air flow meters are essential in measuring the flow rate of compressed air. They can be used in various sectors e.g.; commercial, industrial and also in residential areas. This gas flow meter helps in the regulation of the amount of gas or compressed air to be used.

Thermal mass flow meter to be used as digital compressed air flow meter

Thermal mass flow meter to be used as digital compressed air flow meter

A thermal mass flow meter is a flow measurement instruments that measures the mass flow of compressed air in pipes. It is widely used in thermal industries. Unlike other gas or air flow meters, this one does not require correction of temperature and pressure. It has the following features;


  • Digital compressed air flow meter with electronic display to show mass flow rate and total flow
  • Electronic flow meter with current or pulse output
  • Digital air flow meter option with MODBUS or Hart Protocol
  • Thermal mass flow meters are accurate. Even with a range of flow rates, this air mass flow sensor provides perfect measurements.
  • The flow meter can measure compressed flow in many different sizes of pipes. Insertion type thermal mass flow meter can be used in large pipeline measurement
  • This flow sensor is compact thus it has no movable parts. This helps reduce maintenance practices to the meter.
  • It has sensors that are temperature resistant hence digital thermal mass flow meter can also indicate temperature also


Digital Vortex flowmeters for compressed air flow measurement

Digital Vortex flowmeters for compressed air flow measurement

The vortex flow meter is an advanced instrument that measures the volumetric flow rate of air or compressed air. The electronic vortex flow transmitter has the following features;


  • It has a non-leaking feature. With this, no leakages of compressed air or gas  through the pipes.
  • The vortex flowmeter sensor is of durable materials that make it long-lasting.
  • The flow meter is temperature resistant. However hot the gas is, it does not damage the flow meter
  • The flow transmitter is easily adjustable. It has movable parts that can be easily detached and attached even when the gas is flowing.
  • Digital Vortex flow meter has display, 4-20mA output or frequency output
  • Digital vortex flow meter with battery or 24VDC power supply


Advantages of rotameters to be used as digital compressed air flow measurement

Advantages of rotameters to be used as digital compressed air flow measurement

Rotameters are tools used in measuring the flow of gas or air through tubes and pipes. Rotameter can be made with flow transmitter and digital display to show air flow rate and total flow.

Below are some advantages or variable area flow meter

Rotameters use standard pipe fittings. With this, even straight pipes are usable.


  • They are made from cheap materials hence they are economically friendly.
  • Rotameters can be installed in areas without power since they only require gravity to measure the flow of compressed air.
  • It uses a linear scale to measure hence its readable in the same degree of accuracy in a full range.
  • Rotameters are easy to stress hence no need to worry when fixing one.
  • Digtial variable area flow meter can easily install it with alarms and switches for easy operation.
