avoid overspeeding on start-ups.
POSITIVE DISPLACEMENT METERS
At your request, these meters may have a non-return valve installed in the inlet port.
This valve will not allow pressures caused by thermal expansion to pass to the water
system's side of the meter. Take particular care that the meter is installed with the
direction of flow as indicated by the arrow cast in the meter case. Check your local
codes for pressure relief requirements. AMCO Water Metering Systems Inc. assumes
no responsibility for damages.
At your request, these meters may have a plastic main case. Plastic meter cases will
not conduct electricity. Check your local codes for grounding requirements. AMCO
Water Metering Systems assumes no responsibility for the electrical grounding of its
water meters.
At your request, these meters may have a frost protection device. Take particular care
to install these meters in a location where water damage will not occur if the frost
device releases or functions. AMCO Water Metering Systems assumes no
responsibility for damages.
FIRE HYDRANT METERS
This meter has a restrictor plate installed in the outlet port. A restrictor plate will
suppress the flow capacity of the meter and protect it from overspeeding when water
throughput flows to atmosphere. Take particular care to install and start-up the meter
as recommended above. AMCO Water Metering Systems assumes no responsibility
for damages.
At your request, this meter may have a check valve installed in place of the restrictor
plate. This valve will not allow pressures caused by reverse flow conditions to pass to
the water system's side of the meter. Take particular care that the meter is installed with
the direction of flow indicated by the arrow cast in the meter case. Check your local
codes for pressure relief requirements. AMCO Water Metering Systems assumes no
responsibility for damages.
