Abstract
A fluid system such as a fire sprinkler system or a device such as a pressure reducing valve is tested by fitting to the system or device at least one outlet device whose characteristics are known, causing fluid to flow under test conditions, and measuring the fluid flow through the outlet device to give an indication of which flow would take place under normal operating conditions. The outlet device may be a flow restrictor.
Claims15
A method of establishing an operating characteristic of a fluid system or device having an inlet and at least one outlet, comprising providing the device, system or a model of the system with at least one outlet device having predetermined characteristics, causing flow of fluid through the device system or model under test conditions;
- measuring the flow of fluid at said at least one outlet;
- and deriving from said measured flow an indication of said operating characteristic.
A method according to any one of the preceding claims wherein said fluid caused to flow in said test conditions is a gas.
Apparatus for testing a pressure reducing valve, comprising a flow restricting means for connection to the outlet of the valve, and flow measuring means for measuring the flow of fluid through the valve and flow restricting means.
A method or apparatus substantially as hereinbefore described with reference to and as shown in the accompanying drawings.
Any novel feature or novel combination of features described herein and/or in the accompanying drawings.
