¨ (Meter Initiated systems ONLY)
4.4.3 Flow Sensor(s)
¨ (1.5” Plastic Turbine Meter)
A flow sensor package shall be provided consisting of an turbine-type Hall Effect; the package shall include a
total of _____ flow sensors with fittings.
The fitting provided shall be a 1-1/2 inch threaded Noryl housing. A 4-foot length of cable shall be provided for
direct connection to the system controller.
The flow sensor package provided shall be functional within the flow range of 1 to 60 gpm.
The operating temperature/pressure range of flow sensor fittings shall be 34°F - 100°F at 140 psi max.
The wetted surfaces of the flow sensor shall be constructed of non-corroding materials.
The flow sensor shall have an accuracy to 2% over full range.
¨ (2.0” Meter)
A flow sensor package shall be provided consisting of an insertion-type Hall Effect flow transducer with an
appropriately sized installation fitting; the package shall include a total of _____ flow sensors with fittings.
The fitting provided shall be 2.0 inches, compatible with the specified piping. It will be designed to allow ease of
removal of the sensor for inspection without modification of the piping system. A 25-foot length of cable shall be
provided for direct connection to the system controller.
The flow sensor package provided shall be functional within the flow range of 3 to 275 gpm and will be provided
with a threaded tee flow sensor installation fitting.
The operating temperature/pressure range of flow sensor fittings shall be 34°F - 100°F at 140 psi max.
The wetted surfaces of the flow sensor shall be constructed of non-corroding materials such as polypropylene,
black Polyvinylidene (PVDF) and titanium.
The flow sensor shall have an accuracy to 1.5% over full range.
4.5 EXCHANGE RESIN
The ion exchange resin shall be virgin high capacity “standard mesh” of sulfonated polystyrene type stable over
the entire pH range with good resistance to bead fracture from attrition or osmotic shock. Each cubic foot of
resin will be capable of removing 30,000 grains of hardness as calcium carbonate when regenerated with 15
lbs. of salt. The resin shall be solid, of the proper particle size of 20-50 mesh, U.S. standard screen and will
contain no agglomerates, shells, plates or other shapes that might interfere with the normal function of the water
softener. The resin shall be manufactured to comply with the food additive regulation 21 CFR 173.25 as set
forth by the USFDA.
The system shall include _____ cubic feet of exchange resin per vessel and a total of _____ cubic feet of resin
for the system.
4.6 BRINE SYSTEM
Provide a complete brine system consisting of a plastic tank, salt platform, brine well, an automatic brine valve
and all necessary fittings for operation with the water softening system. The system shall consist of a combined
brine measuring and salt storage tank with salt platform. The tank will be sized ____ inches x _____ inches; the
system will include a total of _____ brine tank(s).
The brine tank will be equipped with a float operated non-corrosive field serviceable brine float valve for
automatic control of brine withdrawal and fresh water refill.
The brine valve will automatically open to admit brine to the resin tank during eduction and close automatically
providing positive shut-off to prevent air from entering the system. The brine valve will also regulate the flow of
soft water into the brine tank during refill. The brine valve works with the timed fill feature of the main operating
