Description
Operating Instructions for all versions of 515/8510 and 2536/8512
Simple to install with time-honored reliable performance, Signet 515 and 2536 Rotor-X
Paddlewheel Flow Sensors are highly repeatable, rugged sensors that offer exceptional
value with little or no maintenance.
Signet 515 and 2536 sensors measure liquid flow rates in full pipes and can be used in
low pressure systems.
• The many material choices including PP, PVDF, and PVC (2536 only) make this
model highly versatile and chemically compatible with many liquid process solutions.
• Sensors can be installed in DN15 to DN900 (½ to 36 in.) using Signet's
comprehensive line of custom fittings, except the PVC 2536 version which can be
installed in DN15 to DN100 (½ to 4 in) pipes using Signet's comprehensive line of
custom fittings as well.
• These custom fittings, which include tees, saddles, and weldolets, seat the sensor to
the proper insertion depth into the process flow.
• The sensors are also offered in configurations for wet-tap installation requirements
except 2536 PVC version.
515/8510 Advantages:
• Flow rate range 0.3 to 6 m/s (1 to 20 ft/s)
• Installs into pipe sizes DN15 to DN900 (½ to 36 in.)
• Wide Turndown Ratio of 20:1
• Sinusoidal frequency output capable of driving a self-powered flowmeter (Model 5090)
• Self-powered
• Highly repeatable output
• Chemically resistant materials
• Easy to replace rotor
2536/8512 Advantages:
• Flow rate range 0.1 to 6 m/s (0.3 to 20 ft/s)
• Installs into pipe sizes DN15 to DN900 (½ to 36 in.)
• The 2536 PVC version installs into pipe sizes DN15 to DN100 (½ to 4 in) for
concentrated Sodium Hypochlorite 12.5% applications
• Wide Turndown Ratio of 66:1
• Open-collector output
• High resolution and noise immunity
• Chemically resistant materials
• Easy to replace rotor
• Sodium Hypochlorite transfer/injection/batching (3-2536-U0)

2Signet 515/2536 Rotor-X Flow Sensors
Georg Fischer Signet products are manufactured in a variety
of wetted materials to suit various liquids and chemicals.
All plastic materials including typical piping types (PVC, PVDF,
PP and PE) are more or less permeable to contained media,
such as water or volatile substances, including some acids.
This effect is not related to porosity, but purely a matter of gas
diffusion through the plastic.
If the plastic material is compatible with the medium according
to the application guidelines, the permeation will not damage
the plastic itself. However, if the plastic encloses other
sensitive components, as is the case with GF Signet plastic
paddlewheel sensors, these may be affected or damaged by
the media diffusing through the plastic body and rotor.
Failures of PVDF paddlewheel sensors when used in hot nitric
acid applications have been reported. PVDF is known to allow
for substantial permeation of nitric acid constituents without
being damaged itself. No clear guideline can be given here,
since the damaging effect to the sensor is highly dependent
on temperature, pressure and concentration.
Utilizing sensors in applications with aggressive substances is
possible. On special request GF Signet can provide sensors
with a different internal resin encapsulation (potting) that will
delay the damaging effect of acids to the sensors.
For all Special Product inquiries or to place an order, please
email signet-specialproduct@georgfischer.com.
1. Depressurize and vent system prior to installation or removal.
2. Confirm chemical compatibility before use.
3. DO NOT exceed maximum temperature or pressure specs.
4. ALWAYS wear safety goggles or faceshield during
installation and/or service.
5. DO NOT alter product construction.
Below are Safety Instructions from the pipe fittings
instruction sheet:
6. Do not use this product for any purpose other than for
which it was designed.
7. Use with liquids only.
Warning / Caution / Danger
Indicates a potential hazard. Failure to follow all
warnings may lead to equipment damage, injury,
or death
Personal Protective Equipment (PPE)
Always utilize the most appropriate PPE during
installation and service of Signet products.
Pressurized System Warning
Sensor may be under pressure, take caution to
vent system prior to installation or removal.
Failure to do so may result in equipment damage
and/or serious injury.
Hand Tighten Only
Overtightening may permanently damage product
threads and lead to failure of the retaining nut.

Paddlewheel Retaining Nuts:
Red (515), Blue (2536), and Gray (2536)
The retaining nuts of paddlewheel sensors are not designed
for prolonged contact with aggressive substances. Strong
acids, caustic substances and solvents or their vapor may
lead to failure of the retaining nut, ejection of the sensor and
loss of the process fluid with possibly serious consequences,
such as damage to equipment and serious personal injury.
Retaining nuts that may have been in contact with such
substances, e.g. due to leakage or spilling, must be replaced.
Paddlewheel Maintenance:
Paddlewheel flow sensors are subject to wear and may
require maintenance and replacement of mechanical parts
(rotors, pin, O-rings, bearings, retainers, etc.). The frequency
of recommended maintenance will vary based upon
application specifications, characteristics of the measured
fluid, and installation details. These can include, but are not
limited to: process flowrate, occurrence of water hammer, fluid
corrosiveness and abrasiveness, sensor installation relevant
to other equipment.
GF Signet offers individual replacement parts and rotor
replacement kits, which include replacement instructions,
allowing customers to perform field maintenance and reduce
application down-time. Please refer to the Paddlewheel
Replacement section (page 5) or contact your local GF Sales
Representative with any questions.
515, 2536, 8510, 8512, 2537 Only:
To support our customers, the GF Signet Repair Department
offers services to recertify the plastic paddlewheel products to
factory specification. Contact your distributor or visit
www.gfsignet.com for more information.
WARNING!
Warranty Information

current warranty statement.
All warranty and non-warranty repairs being returned must
include a fully completed Service Form and goods must be
returned to your local GF Sales office or distributor.
Product returned without a Service Form may not be
warranty replaced or repaired.
Signet products with limited shelf-life (e.g. pH, ORP, chlorine
electrodes, calibration solutions; e.g. pH buffers, turbidity
standards or other solutions) are warranted out of box but not
warranted against any damage, due to process or application
failures (e.g. high temperature,

Location of Fitting
• To remove the rotor, insert a small screwdriver between the rotor and the ear of the sensor.
• Twist the screwdriver blade to flex the ear outward enough to remove one end of the rotor and pin.
• DO NOT flex the ear any more than necessary! If it breaks, the sensor cannot be repaired.
• Install the new rotor by inserting one tip of the pin into the hole,
then flex the opposite ear back enough to slip rotor into place.

• Lubricate O-rings with a non-petroleum based, viscous lubricant (grease)
compatible with the system.
• Using an alternating/twisting motion, lower the sensor into the fitting, making sure the
installation arrows on the black cap are pointing in the direction of flow, see Figure A.
• Engage one thread of the sensor cap then turn the sensor until the alignment tab is seated in
the fitting notch.
Hand tighten the sensor cap.
DO NOT use any tools on the sensor cap or
the cap threads and/or fitting flange threads
will be damaged, see Figure B.

• Use 2-conductor shielded cable for cable extensions.
• Cable shield must be maintained through cable splice.
• Refer to your instrument manual for specific wiring

Rotor Replacement Procedure
To ensure the fluid velocity profile is fully
developed, without distortion from piping system
components, please adhere to the recommended
straight run geometry.
Horizontal pipe Runs
To minimize adverse effects of air pockets, sediment, or excessive rotor wear (Paddlewheels), avoid
mounting the flow sensor at the top of the pipe (0º), bottom of pipe (180º), or the sides (90º from
vertical.)
Vertical Pipe Runs
Mount flow sensors in any direction. To ensure pipe is flowing full, with some back pressure, it’s highly
recommended the fluid flow is upward.
Gravity and Discharge Lines
It’s recommended to install a trap to ensure pipe is full during flow conditions, and to minimize
air pockets.

K-Factors
H-Dimensions
A K-Factor is the number of pulses a sensor will generate for each engineering unit of fluid that passes the sensor. K-Factors for water
are listed below in U.S. gallons and liters. For example, in a 1-inch PVC pipe, the 515 paddlewheel generates 172.07 pulses per gallon
of water passing the rotor. K-Factors are listed for pipes up to 12 inches. For pipes over 12 inches, consult your Signet distributor.
