description.

“Meter shall be of a flow meter with a positive displacement design having rotary motion

without axial thrust or flow disruption. No eccentric, sliding, reciprocating or oscillating parts to

induce excess liquid shear or liquid compressibility within meter element. Meter shall have three

rotors that rotate in unison within the measuring chamber. Rotary parts to be horizontally

supported on both sides by solid support bearings and rotor journals of materials compatible with

DESIGN

The TCS Model 700 series flow meter is a simple

and efficient design. The meter consists of a single

fluid chamber that contains a single blocking rotor

and two displacement rotors whose rotation is

synchronized with mating gears. As the fluid

enters the fluid chamber, the blocking rotor is

forced to rotate. The displacement rotors, also

rotating in conjunction with the blocking rotor help

direct the fluid flow through the chamber and to the

outlet. The linear flow of the fluid is thus

translated into rotary motion in the meter. The

output of the meter is picked up from the rotation

of the blocking rotor and transmitted to a register or

pulse transmitter.

The rotors in the meter are designed to operate at close tolerances to one another and the wall of

the fluid chamber. There are slight gaps between the rotors and the chamber wall. Because of

this, it is important that the meter be properly applied for the flow rate and operating pressure of

the system.

Because the fluid flowing through the meter is redirected only slightly from its natural flow,

there is very little pressure drop across the meter, unlike other meters that use multiple measuring

chambers.

The meter design uses high quality long life materials for the rotor bearings and journals. Since

there is no contact between the rotors and the fluid chamber wall, these critical components have

a long life expectancy.

Calibration of the meter involves adjusting the rotation of the output shaft relative to the rotation

of the internal rotors of the meter. This is accomplished by changing the settings on an adjuster

device. Calibration of the meter is discussed in detail in the section Meter Calibration.

METER SELECTION FACTORS

WEIGHTS&MEASURES

Before any meter can be specified, knowledge of each application is required. If the liquid is to

be sold through a metered delivery, domestic or international certification from a governing body

may be required. Total Control Systems strictly adheres to all domestic and international

metrology conformance regulations for the custody transfer of fluids. For questions regarding

weights and measures approvals or other issues, please consult factory.

The 700-meter’s accuracy (percent of error over or under the zero – error level) remains within

design parameters (+/- 0.15%) over its minimum rated flow range to its maximum rated flow

range for custody transfer meter requirements. This percentage meets or exceeds the Wholesale

and Vehicle accuracy requirements for accurate custody transfer of product, as specified in the

National Institute of Standards and Technology (NIST) Handbook 44.

PRODUCT CHARACTERISTICS

A) Material Compatibility

The product intended to be measured must review Total Control Systems CHEMICAL

COMPATIBILITY on page 23 to 35 to find the suitable materials and meter type. Materials

incompatible with product will potentially reduce accuracy, operation life, contaminate liquid

and may be harmful to others.

B). Flow Rate

The minimum and maximum system rate of flow must be determined for the selection of

flow meter. The flow rate of the system is dependent upon the product viscosity; the desired

meter configuration, the systems pump capabilities, and the plumbing configuration.

C) Pressure

The maximum working pressure allowed should be reviewed under flow meter type and

pressure rating. All meters meet the European Pressure Equipment Directive (PED) No.

97/23/EC. Failure to adhere to the maximum allowable pressure may potentially cause a seal

leak or casting rupture.

- 7 -

D) Temperature

The operating temperature has a great effect on the meter seals and its relationship to the

maximum pressure allowed with the flow meter castings. It will be necessary to reduce the

maximum rated working pressure as the operating temperature increases. Any metering

system operating over 160F (71C) will require extra clearance rotors to compensate for

material expansion. Any metering system operating over 180F (82 C) will require at least a

one (1) foot registration extension to protect the registration devices. Increase in temperature

may increase the corrosion rate of some products.

Teflon -20F to 500F -30C to 260C

300F/150PSI

E) Lubricity

The lubricity or non-lubricity of the product will determine the bearing sleeve material

suitable for use. Products with no lubrication will require the use of Carbon Graphite or

Ceramic bearing sleeves. Products with lubrication will reduce friction between two metal

surfaces and help dissipate heat.

F) Suspensions & Suspended Solids

Products with a low percentage of soft suspensions or suspended solids will require clearance

rotors and/or Ceramic bearing sleeves to protect the meter from its abrasive effects. High

percentages (5%) of suspensions or suspended solids, or any hard solids, such as sand, are

not recommended for the 700 series meter. Due to the very tight machining tolerances any

solid, larger than the thickness of a piece of paper, has the potential of stopping the flow

through the meter and can cause damage to the meter.

- 8 -

G) Foreign Materials

Products that are to be measured may have foreign materials present. The inlet side of any

positive displacement meter should be equipped with a strainer. Matching the strainer size or

one size larger, with an appropriate size screen will protect the meter and accessories from

damage in the system. A minimum of 40-mesh screen is recommended for petroleum service.

H) pH

The metal resistance to the effects of high or low

PH is difficult to calculate because of the varying

concentrations and corrosiveness of properties.

This is a generalized rating for pH resistance.

I) Viscosity

Viscosity is the property of a fluid that is a measure of its resistance to flow. Among the

earliest to express this quantitatively was Sir Isaac Newton. He reasoned that the viscosity of

a liquid was proportional to its shear stress (or resistance to shear). Liquids that behave in

this manner are referred to as “Newtonian” liquids and are typically by petroleum fluids,

water and similar chemicals.

Other types of fluids are grouped into a general category called “Non-Newtonian” which

includes dilatants, plastic, pseudoplastic and thixotropic. Liquids in this group are

characterized by viscosity that changes with the rate of shear as compared to the Non-

Newtonian fluids where viscosity is basically constant with shear and flow rate. As a

consequence, Newtonian fluids are much easier to predict with regard to their performance

through a flow meter than are the Non-Newtonian liquids.

Many of the more viscous liquids pumped through the 700 series rotary flow meter are

plastic and pseudoplastic and as such are reduced in effective viscosity after being pre-

sheared by the pump. The diagram below shows how viscosity varies as a function of shear

rate on various types of liquids.

1) Thixotropic Liquids (Plastic and Peudoplastic)

Viscosity decreases as shear rate increases. Typical liquids include

Gels, Latex paints, lotions, Shortening, Mayonnaise, Printers Ink, Hand

cleaner and Yeast.

2) Newtonian Liquids –Viscosity remains unchanged with shear.

3) Dilatants Liquids –Viscosity increases as shear rate increases. Most

liquids in this category are unsuitable with PD flow meters; these

include Clay, Slurries and some confectionary bases.

J) Pressure Loss

The pressure drop is the difference between of the inlet and outlet pressure of the flow meter

while operating. When measuring a liquid, the pressure drop will increase as the flow rate

increases. When the metering system has accessories such as an air eliminator or valve,

these items will be approximately the same pressure drop through equivalent size meter.
