glass flow indication sight glass / flange

Mival flow indicators are devices that can be assembled inside pipelines. The pipelines should be cleaned for removing the impurities in them before installing the flow indicators so that the effective functionality of the device can be ensured. Device can be cleaned well wby making use of compressed air. Flow indicators need to be fixed in right position at pipeline. Gaskets should be inserted between flanges for centring them to the possible extend. Gaskets can be deformed effectively by fitting the bolts in the holes of flanges and tightening them for maintaining opposed sequence diametrically. This is the best device available as flow indicator and should be used inside pipelines.
