Abstract
The present application relates to a particle monitoring system, to a portable microbial air sampler, to a method for monitoring particles in a sample fluid, such as gases and particularly compressed gases, and to a method for calibrating/adjusting a particle monitoring system.
Claims20
A particle monitoring system (1) comprising:
- a sampling section (2) for performing a sampling process on a sample fluid flowing through the sampling section (2);
- and
- a sensor arrangement (3) for determining a volume flow rate of the sample fluid flowing through the sampling section (2), the sensor arrangement (3) associated to a flow path (7) downstream of the sampling section (2) through which the sample fluid flows, in operation, after having passed the sampling section (2),
- wherein the sensor arrangement (3) comprises a flow sensor (4) for determining a mass flow rate of the sample fluid flowing through the flow path (7) downstream of the sampling section (2).

A method for monitoring particles of a sample fluid, the method comprising:
- sampling particles in a stream of the sample fluid flowing through a sampling section (2);
- and
- determining a volume flow rate of the stream of sample fluid flowing through the sampling section (2) by:
- determining a mass flow rate of the sample fluid flowing through a flow path downstream of the sampling section (2),
- determining an absolute pressure in the flow path upstream of the position where the mass flow rate is determined and downstream of the sampling section (2), and
- calculating the volume flow rate of the sample fluid flowing through the sampling section (2) based on the determined mass flow rate and the determined absolute pressure.
