INSTALLATION GUIDE
RPFS
Adapter Tee keyway fittings are available in:
1. PVC Class 18 Cat. 19 Slip tees (F-glue-ends) pressure pipe
Sizes: 20, 25, 32, 40, 50, 65, 80 & 100 mm.
PVC high pressure saddle clamps: 40, 50, 80 and 100mm.
2. Galvanized Iron threaded connections:
BSP (F): pipe sizes 25, 32, 40 & 50 mm;
BSP (M) pipe sizes 80 & 100mm.
3. Gunmetal BSP(m) threaded connection end pipe tube tees 20 mm.
4. Polypipe saddle clamps in pipe sizes 40, 50, 63, 75, 90, 110 mm
5. PVC saddles 40, 50, 80 and 100mm.
6. Stainless steel 25, 32, 40 & 50mm, larger sizes fabricated on request.
7. FOR PIPE SIZES 110mm and larger refer to the RPFS-LS model
**Further custom made fittings are available on request.

pipe adapter keyway nipple - with locknut, which has a 1” OD BSP thread for
screwed insertion into 1”(female BSP) half-sockets which can be welded
directly to pipe, the BSPB fittings can be coupled to any 1” BSP female entries
including saddle clamps.
Installation Conditions
IMPORTANT
: A minimum of 10x pipe diameter before (upstream of) the
sensor and at least 5x pipe diameter after sensor of straight pipe section
must be fitted, with no bends, reductions, enlargements, restrictions, valves
etc within this section. This will help eliminate flow turbulence to ensure
optimum accuracy performance.
The RPFS sensor must measure in a full pipe flow section.
Can be installed in a horizontal, inclined or vertical pipe position.
(Note: If mounted in horizontal or inclined pipe, make sure
insertion position of sensor is at top or 45
from top, not on the underside).

# If connecting to non-ManuFlo equipment, a 2K2 pull-up resistor
may be required between (+) and Pulse.
For extra cable length, use shielded cable only!
WARNING: To avoid electrical interference the RPFS-H and RPFS-L
should not be installed within 30cm of any AC fields, otherwise 50Hz
could be detected and create oscillations.

For >315mm diameter pipes:
Pulses per Litre = 50273 / [ (Pipe diameter in mm)
2.016
]
(2)
NOTE:
Due to gravitational forces, the pulse output value can differ
up to 6% between a vertical flow that is upwards or downwards. Where
possible, perform a calbration check to determine pulse rate given the
pipe diameter and flow conditions. Once calibrated, meter will give linear
and repeatable results within the flow range
