All gas appliances used for cooking, heating, refrigerating or even soldering must be leak tested and flow checked during their manufacture to ensure they are safe for use.
The FCO754 Gas Appliance Leak Detector is designed specifically for Leak Detection in Gas Appliances. When testing finished products for leakage, it is essential to be able to identify and rectify any leaks without having to move the appliance to a rework station. The FCO754 facilitates this by showing a live leak reading. This allows an operator to check and tighten couplings on the appliance with visual feedback of the result.
Appliances which incorporate gas valves will need to be leak tested with valves open and closed. The FCO754 can be configured to operate a series of leak tests on the appliance achieve this.
To reduce the chances of failure at the final appliance test stage, all parts of a gas appliance are leak tested at their manufacturing stage. These parts are tested to a tighter leak specification so that the accumulated leak from all parts does not exceed the leakage allowed for the final appliance. These parts are normally tested using the FCO730 or FCO750 Leak Detectors as the need to rectify leaks using the continuous flow principle does not apply.
Each burner of a gas appliance must be tested to ensure that it produces its specified heat output. This is achieved by measuring the volumetirc flow rate of gas for each burner in its low and high flow positions.
The FCO752 is designed specifically for the flow testing of gas burners/injectors. To do this it has certain unique features over normal volume or mass flow-meters which make it suitable for the job:
All modern appliance manufacturers must keep leak and flow test results for every product manufactured to provide product traceability. Furness Controls leak detectors and flow meters can be intergrated with 1D and 2D Barcoder readers to select the correct sequence of tests for the product, along with the unique serial number of the product under test. In conjuction with the data logging feature and RS232, RS485, LAN and Ethernet communications, this data can be exported to printers, markers, PCs, or across networks.
