Should the discharge valve of a turbine flowmeter be installed upstream or downstream of it?
Thread Content
As the title says. I hope everyone can offer some advice and explain the reasons.
It should be installed upstream; to ensure the service life of the flow meter, a drain valve should be installed before the straight pipe section of the flow meter in order to remove impurities from the fluid.
It is advisable to install filters and bypass pipelines, as this facilitates the maintenance of the instruments. The selection of such instruments actually requires quite specific conditions regarding the medium being handled; if there is enough space, a bypass and filter should be added. The discharge outlet should be located at the front, so that it is easier to carry out repairs in case there are doubts about instrument malfunction.
Installed in front of the valve to ensure there is water in the pipe; if it is installed behind the valve, the pipe will be empty, resulting in false signals being generated
