Upon receipt of the flowmeter carefully inspected it, checking for
any indications of damage which may have occurred during
shipment. Inspect all packing material carefully for parts or
components which may have been packed with the shipment.
Refer to the packing list/invoice for a detailed list of items
included in the shipment.
3.1 General Piping
The MF Series Flowmeters are capable of sensing fluid flow in one
direction only. The meter housing is marked by a flow direction
arrow to indicate the direction of flow through the meter. The
meter must be installed in the piping in the correct orientation to
ensure the most accurate and reliable operation. Care should be
taken in the proper selection of the mating fittings. Size, type of
material, and pressure rating should be the same as the flowmeter
supplied.
When it is expected that flow will be intermittent, the meter should
not be mounted at a low point in the piping system. Solids which
settle or congeal in the meter may affect meter performance.
In order to achieve optimum electrical signal output from the
flowmeter, due consideration must be given to its isolation from
ambient electrical interference such as nearby motors,
transformers, and solenoids.
A typical flowmeter installation is shown below:
Blocking and Bypass valves should be installed if it is necessary to
do preventive maintenance on the flowmeter without shutting
down the flow system. The Bypass valve can be opened before the
Blocking valves are closed allowing the flow to continue while
removing the turbine flowmeter for service.
