About FPP Meters

We thank you for purchasing an FPP Meter for liquid meas-

urement service. FPP Meters, formerly Fluid Power Prod-

ucts, is now a trade name of Tuthill Transfer Systems. FPP

was established in 1980. Since its inception, the company

has been dedicated to manufacturing cost-effective, high

performance flow metering devices for petroleum, industrial,

commercial and municipal service.

Our facilities include computerized order entry and inventory

control, so that you are assured of accurate and prompt de-

liveries. Furthermore, our production personnel ensure that

each order, regardless of size, receives individual attention.

Constant attention to new product development and produc-

tion design, our high standards of manufacture and final

testing are the reasons why FPP Meters meet your most

demanding requirements. With the ‘Waveform’ oval gear

(2003 patent) meter accuracy is better than ever before.

Our meters are used in batching, blending, process control

and to dispense fluids in liquid handling facilities throughout

the World. Service includes gasohol blends, bio-diesel and

special formulation racing fuels.

Principle of Operation

Positive Displacement meters have a measuring chamber,

where inlet & outlet are separated by rotors, a rotating ele-

ment or sliding vanes. As the liquid passes through the flow

meter, it causes the rotors/element/vanes to turn, which

forms the basis for volumetric measurement.

The Oval Gear metering principle is based on two elliptical

(oval) gears, which turn on center on two horizontal shafts

inside a measuring chamber formed by two overlapping cyl-

inders. The oval gears have meshing teeth along their en-

tire circumference, ensuring that the gears will maintain cor-

rect position in relation to each other at all times, without the

use of timing gears.

The volume being transferred from the

inlet to the outlet side (= volume meas-

ured), forms between the oval gear

and the side of the measuring cham-

ber, alternately in the upper and the

lower half of the measuring chamber.

In a full 360° rotation of the gears, four such known volumes

are released to the downstream side of the flow meter.

With precision machining and close internal tolerances, the

slippage is minimal for superior linearity (accuracy) over a

broad turn-down ratio. Oval gear meters are largely unaf-

fected by changes in liquid viscosity.

The TS Series meter is designed to provide:

V●● Assy: Drive to a mechanical register,

including RAD adaptor for the register.

E●● Assy: Electrical pulse signal to an electronic

installation of the electronic register.

. S●● Assy: Electrical pulse signal to a remote

electronic register.

In the two electronic versions, the flow meter is 100% gland-

less with static O-ring seals only. An internal magnet wheel

with 4, 6 or 12 poles turns on a shaft mounted on the gear

plate. As each pole passes by the tip of the pulser (Hall

Effect, Quadrature Hall Effet or Reed Switch type), a square

wave pulse signal is generated.

Standard signal from the Hall Effect pulser is a digital current

sinking output. When a sourcing signal is required, add the

PIA-300 signal conditioner.

Fluid Compatibility

FPP Meters flow meters are available in anodized aluminum

and stainless steel, with a variety of rotor types and seals, to

ensure compatibility with a broad range of liquids. If in doubt

about compatibility with a a specific fluid, please refer to the

FPP Technical Manual. If that publication does not provide

a clear answer, please consult with your authorized FPP

Meter distributor, or Customer Care at the factory.

Do not change service liquid, without consulting with your

authorized FPP Meter distributor.
