Conduit installation
Prevent condensation in any conduit from flowing into the housing by mounting
the flowmeter at a high point in the conduit run. If the flowmeter is mounted at a
low point in the conduit run, the terminal compartment could fill with fluid.
If the conduit originates above the flowmeter, route conduit below the flowmeter
before entry. In some cases a drain seal may need to be installed.
