Pressure meters & Manometers

Accurate pressure measurement and control are important in many industries, both in terms of quality process, good practice, preventative maintenance and perhaps most importantly, as a critical health and safety procedure.

Eurolec provides a range of differential, gauge and absolute pressure measurement solutions with a variety of options.

Our range provides a choice of pressure scales for different applications and different market sectors including gas flow measurement, HVAC, system monitoring, tank level measurement, computer clean rooms, detection of air flow, process plant pressure checks and pressure instrument calibration.


About our pressure meters and manometers

Accurate pressure measurement and control are important in many industries, both in terms of quality process, good practice, preventative maintenance and perhaps most importantly, as a critical health and safety procedure.

Our range of manometers is designed for non-corrosive gauge, differential air or gas pressures measurement in a wide range of industries. Our instruments provide a choice of pressure scales for different measurements including gas flow measurement, HVAC, system monitoring, detection of air flow, process plant pressure checks and pressure instrument calibration.

All Eurolec manufactured instruments come with a 5-year warranty as standard and include a Traceable Calibration Certificate.

Typical applications for our pressure measurement devices include:

  • flue draught measurement
  • gas pressure in heating appliances
  • air conditioning ducts
  • monitoring of filter differential pressure
  • velocity measurement with a pitot tube

What is the difference between a manometer and a pressure meter?

A manometer is a pressure measuring instrument that measures low pressure. They are typically used for measuring gas pressure or low atmospheric pressure and normally measures in mbar. Whereas a pressure meter measures high pressure, non-corrosive air or gas and normally measures in psi (pounds per square inch).

Absolute, gauge or differential pressure?

Users need to know what the difference is between absolute, gauge or differential pressure measurements is so they can use the correct meter for the correct application and avoid errors.

Absolute pressure

Absolute pressure uses absolute zero value as its reference point. This is derived from the scenario where no matter exists inside a space or a perfect vacuum. The best example of an absolute referenced pressure is the measurement of barometric pressure.

Gauge pressure

This is the different between the absolute pressure and the difference between the pressure of the atmosphere. For example, a punctured car tyre with no air in it would read 'zero' on a tyre pressure gauge, even though it still contains atmospheric air molecules. Gauge pressure meters are designed to measure this difference. These measurements are known as gauge pressure measurements.

Differential pressure

Differential pressure is essentially the difference in pressure between two given points where the reference pressure may not be zero or the atmospheric pressure but some other value instead. It is a type of pressure measured within different industries using differential pressure sensors.  A typical application would be the measurement of the flow of gas along a pipeline as flow depends on the pressure difference between the ends of the pipe.
