Electronic Propelller Meters
'Drop in' replacement for
Masterflo Propeller Meters
Description
The FM112 and FM114 Propeller meters
are drop-in replacements for Sparling's
Masterflo meters.
The FM112 is identical in construction to
Sparling's FM102 meters except that the
FM112 features a custom coverplate and
propeller center line dimension ('M
Dimension') to allow this unit to replace
Masterflo propeller meters without any
changes to the piping or meter tube. The
FM114 is identical in construction to
Sparling's FM182 meters except that the
FM114 features a custom coverplate and
propeller center line dimension ('M
Dimension') to allow this unit to replace
Masterflo propeller meters without any
changes to the piping or meter tube.
These meters are designed to provide
accurate and reliable flow measurements
where mainline service is required in
municipal and industrial environments.
These meters have a proven design and a
reputation for rugged, continuous, duty
with minimal required maintenance.
Sparling's propeller meters are ideally
suited for clean water applications where
the temperature of the water does not
exceed 100°F and suspended solids do not
exceed 0.5%.
Certified Accuracy
Accuracy is within 2% of actual flow for the
specified meter range. This accuracy is
guaranteed by certified wet calibration at
three test points in Sparling's NIST
traceable primary flow laboratory. Each
meter is tested at low flow, mid-range, and
high flow. A test certificate is provided with
each meter.
Installation
Meters must be installed in full flowing
suction or discharge lines. Avoid valves,
fittings or obstructions immediately
upstream of the meter which may cause
jetting or non-symmetrical flow profiles. It
is recommended that a minimum of five
straight pipe diameters be maintained
upstream and one diameter downstream
of the flow meter.
Registration of flow is shown on a register
which can be furnished in any standard
units(i.e. gallons, cubic feet, acre-feet,
ettc.). This register is a separate item. For
FM112 please specify a FT191 or FT193.
For FM114 please specify a FT194-II.
Note if a new meter tube is required,
please specify FM102 / FM182 / FM182 /
FM182 / MainLine / MainLine meters.
