Seametrics IP80 Series User manual

General Information
The IP80 Series are impeller-type insertion meters de-
signed for use in pipe sizes 1/2" to 8". High-quality jewel
bearings and nickel-bound tungsten carbide shaft are
used for maximum life and extreme low friction. Bodies
are machined from solid rod for maximum precision. Low-
flow performance is superior. The rotation of the rotor is
detected by a non-drag Hall-effect sensor. Output is a
pulse-type square wave, which can be sent long dis-
tances (up to 2,000 feet) without a transmitter. This sig-
nal can be connected directly to SeaMetrics controls, as
well as PLC's, counters, and computer cards.
SeaMetrics IP meters are ideal for chemical proportion-
ing applications. If no display is required, a simple di-
vider such as the PD10 provides adjustable pump pac-
ing. For rate and total display, as well as pump pacing,
the FT415/420 flow indicator can be mounted directly
on the IP80 Series, or remotely on a wall or panel.
The IP80 Series require special fittings, since they are
not depth-adjustable as are the IP 100/200 series meters.
Installation in the fitting ensures correct depth placement
in the pipe. Fittings are available in PVC, brass, and
stainless steel. Sensors are available in brass, 316 stain-
less steel, PVC, and polypropylene. In plastic pipe
3"-8", use an IP82 sensor, which is 1.00" longer than the
IP81 to accommodate the larger fittings.

Installation
Fitting Installation. IP80 Series meters require spe-
cialfittings. Themeterfitting must first be installed in the
pipeline. Straight pipe of at least ten times the diameter
upstream of the meter and five diameters downstream
are strongly recommended. Inadequate straight pipe,
especially downstream of an elbow, change in pipe di-
ameter, or partially-opened valve, can result in signifi-
cant inaccuracy. Typically this inaccuracy is in the form
of the meter reading high. Some IP80 Series meter fit-
tings are supplied with upstream straight pipe.
Meter Installation. After the meter fitting is installed in
thepipeline,themetercan beinstalledin thefitting. Press
the meter into the fitting as far as it will go. Then retain
the meter in place by inserting the u-pin. This pin
canbe installed from eitherside. It is sometimes neces-
sary to rotate the probe back and forth slightly to start
the pin into the slots on the probe. Slide the pin in as far
as it will go.

nal lead.

IP80 Series Connections
In the larger sizes, the length provided is less than ten
diameters upstream and five downstream. It is not ad-
visable to connect directly to the end of these fittings
withaflow-disturbingdevice such as a valve or elbow. If
possible, straight pipe should be added to these fittings.
A PVCfittingisusually installed by solvent welding. The
stainless steel and brass meter fittings have female pipe
threads,requiringtheappropriatemalethreadedfittings.
Saddle fittings (size 3" and above) require a hole to be
cut in the pipe. The recommended hole size is 1-3/4".

K-factor. If the IP80 Series meter is ordered with its
fitting, the meter is factory calibrated in the fitting. A K-
factor (meter factor) is indicated on the side of the fit-
ting. This represents the actual number of pulses per
gallon the meter produced during the factory flow test.
This number can entered into an FT415/420 or FT5210
flow indicator to make it read properly. If a pulse divider
is being used, the K-factor is the starting point for calcu-
lating the divider number.
!
Caution: Never remove the u-
clip retainer when the pipe is
underpressure. Alwaysremove
pressure from the pipe before
attempting to remove the meter.
Removal under pressure may result in damage
or serious injury.

white (signal) Re-connect if necessary
Incompatible control Does control: 1) provide 6-24VDC power; 2) accept current sinking
inputs Contact SeaMetrics
Damaged or missing rotor Remove meter and check visually
for free spinning Obtain new rotor and replace
Inaccurate metering Not enough straight pipe between
meter and flow disturbance See recommendations, measure Move meter away from flow disturbance or field calibrate
Maintenance and Repair

Rotor Replacement. Rotors are easily field-replaced.
Shaft and rotor are a single unit, and are not replaced
separately. If replacement is due only to normal shaft
wear, bearing replacement is probably not necessary.
If the rotor has been damaged by impact, the bearings
should also be replaced. Rotor and bearings can be
ordered as a kit, Part No.25901. Follow these steps:
1. Unscrew the threaded bearing housings to expose
the shaft ends. If bearings are being replaced, back
them completely out.
2. Remove the rotor. Put the new rotor in its place.
3. Thread in one bearing housing part way, then the
other. Take care to start the end of the shaft into the
bearing hole before tightening further.
4. Screw in bearing housings until they bottom. Note:
Do not use excessive force.
5. Checkforfree spin. Blowinglightlyonthe rotorshould
result in it spinning rapidly and coasting to a smooth
stop.
Sensor Replacement. It is very unusual for a sensor
torequirereplacement in normaluse. Theprimarycause
of sensor failure is overvoltage (inadvertent connection
of line voltage, for example) or incorrect polarity on
hookup. The sensor is replaced by removing the the
strain relief, then threading out the sensor retainer plug.
Removethe entiresensorcapsuleby pullingonthe cable.
The new sensor capsule can then be installed. It is impor-
tant to orient the sensor capsule properly. Replace the re-
tainer plug, and then replace and tighten the strain relief.
