With efficient measurement due to absolute pressure compensation the testo 314 independently compensates fluctuations in absolute pressure during volume flow measurement via absolute pressure compensation.
Zeroing phase for connected pipe
To determine ΔP efficiently and quickly, zeroing to ambient air pressure takes place while the measurement is in progress, thus eliminating interruptions and removal of pipes.
Measuring using standard test pressure compensation with feeding unit.
The flow test which is independent of gas mains, has the advantage that pressure fluctuations in pipes can be compensated. The built in flow pressure controller (gas bubble with gas feeding unit) compensates for fluctuations. The finely adjusted value is displayed along with the leakage amount.
