Claims24
A method for determining an operational condition of a particle detection system, the particle detection system comprising at least one sample inlet for receiving a sample flow from a monitored region, the method comprising the step of:
- conducting an upstream measurement of a flow rate through the at least one sample inlet.
A method of testing the operation of pollution monitoring equipment, the method comprising the steps of:
- measuring the upstream flow rate through at least one sampling inlet of a particle detector system;
- determining an operational condition of the pollution monitoring equipment in accordance with the measured flow rate.
Testing apparatus for pollution monitoring equipment of a particle detector system, the apparatus comprising:
- a flow sensor arrangement adapted to form a sealed fluid communication path between a flow sensor and a sampling inlet of the detector system, wherein the flow sensor determines the flow rate through the sampling inlet so as to allow a determination of an operating condition of the pollution monitoring equipment.
Testing apparatus for testing a particle detector system comprising:
- a connector adapted to sealingly engage a sampling inlet of a particle detector system;
- a sensing device comprising a flow sensor for conducting an upstream measurement of flow through the sampling inlet, wherein the sensing device is operatively connected to a flow data storage;
- an extension means providing sealed fluid communication between the connector and sensing device such that a flow path is formed between the sensing device and the sampling inlet via the connector.
A method of field testing a particle detector system, the method comprising the steps of:
- connecting a flow sensing apparatus to a sampling inlet of an air sampling system;
- measuring the air flow rate into the sampling inlet;
- comparing the measured air flow with a previously measured air flow at the time of commissioning the detector system;
- determining from the comparative measurements whether a component of the detector system requires maintenance.
