Heating & Air Flow

Air flow is a measurement of the amount of air per unit of time that flows through a measurement tool.
The amount of air can be measured by its volume or by its mass. Typically it is measured by volume, but for some applications it is necessary to measure it by mass. Air is a gas, meaning its volume can vary with temperature. The instrument that measures air flow is called an air flow meter. Measuring the airflow is necessary in many applications such as ventilation (to determine how much air is being replaced) and engines (to control the Air–fuel ratio).

Differential pressure, or DP or ∆p, is simply the difference between two applied pressures.A differential pressure gauge is a visual indicator, designed to measure and illustrate the difference between two pressure points within a process system. A differential pressure gauge simplifies the process by finding the difference between the points

The flue gases arising from the combustion contain CO2, oxide or soot particles, amongst other things. These pollute the environment, have a negative effect on the climate and conceal numerous health risks for human beings. That is why it is absolutely essential to design combustion processes in a more efficient way, to optimise thermal processes and above all to reduce emissions.

 

Flue gas analysis

Flue gas analysis

The flue gas measurement for a heating system helps to establish the pollutants released with the flue gas  and the heating energy lost with the warm flue gas.

  • Ensuring the atmosphere is contaminated as little as possible by pollutants
  • Using energy as efficiently as possible.

Pressure measurement

Pressure measurement

Standard readings taken during services of domestic heating systems include checking the gas pressure on the burners. This involves measuring the gas flow pressure and gas resting pressure.

  • Optimum flow pressure for gas boilers between 18 to 25 mbar 
  • Avoid shut-downs of the heating system

Leakage test

Leak test

The leak test (or more aptly, serviceability test, also known as leakage measurement) for the pipeline system is to be repeated every 12 years using a measuring instrument.

  • The gas pipe is always tested in operating conditions/with operating pressure 
  • Check whether gas is leaking from the pipe and how much

air flow

For differential pressure measuring instruments, you can also use our anemometers or multifunction measuring instruments to measure air flow velocity – this are also suitable for analyzing indoor air quality.

  • Comprehensive range of measuring functions using optionally available accessories – e.g. anemometers, moisture sensors, lux and degree of turbulence sensors
  • Carry out all the measurements you need to inspect and adjust ventilation and air conditioning systems and to check the quality of the indoor air.
