Ryton® resins are virtually unaffected by aliphatic and aromatic hydrocarbons, chlorinated and
fluorinated hydrocarbons, and most acids and base solutions. The resins, however, may be attacked
by hydrochloric acid media above 200EF in concentrations above 10%. Also, some aqueous mineral
acids and few chlorinated solvents could somewhat attack the resins.

INSTALLATION AND INITIAL OPERATION
Installation
The “CRA” Meter has high resistance to shock while it is operating because of the supporting effect
of the fluid. This resistance is greatly reduced when the meter is out of the line or inoperative.
MECHANICAL EQUIPMENT DAMAGE
Great care should be taken to prevent shock.
Failure to handle the meter with care during installation, removal or shipment may result in
damage to the meter.
If sealing compound is used on piping during meter installation, use it sparingly to avoid fouling
meter parts. Absolute cleanliness of meter internals is important, and precautions should be taken
to prevent entry of foreign matter. Use a strainer upstream of the meter tube section. Another
common cause of meter malfunction, due to fouling of the rotor, is objects left inside the pipeline.
MECHANICAL EQUIPMENT DAMAGE
Flush and clean piping system prior to meter installation.
Failure to maintain absolute cleanliness of meter components may result in damage and
improper meter operation.
SECTION 2

DANIEL CRA LIQUID TURBINE METERS
Daniel Method of Aligning Meter Tube Flange to “CRA” Meter Flange
Internal alignment throughout the metering section is vital to prevent offsets, steps or gasket
protrusion within the bore which could cause disturbance to the flow pattern. Alignment is
accomplished by dowel-pinning.
On all Daniel raised face flanged “CRA” Meters and “CRA” Meter Tubes three knock-out dowel
pin holes are drilled in each flange for alignment of the bore of the meter to the bore of the meter
tube.
On ANSI Class 150 and 300 meters and meter tubes where the dowel pin holes are located tangent
to the raised face, female face-type gaskets are used.
On ANSI Class 600 through 2500 meters and meter tubes where the dowel pin holes are located
beyond the inner bolt circle, series-type gaskets are used.
Care should be taken not to allow the gasket to protrude into the flow stream upon installation.
It is recommended that dowel pins be removed after flange bolt-up and grease packed in the holes
to prevent rust.

INSTALLATION AND INITIAL OPERATION
DANIEL CRA LIQUID TURBINE METERS

Recommended Piping Layouts
Maximum accuracy of a turbine meter requires that the fluid stream be as free of swirl as possible.
The forward and rear rotor supports provide a slight straightening effect, but for best results it is
recommended that the meter be equipped with adequate upstream fluid straightening devices. Flow
control valves should be located downstream of the meter.
Meter Tubes with Straightening Vanes
Small Diameter Meter Tubes
Small diameter meter tubes (under 2") are not normally supplied with straightening vanes. For the
average installation, 20 diameters of straight up-stream pipe should be provided for adequate flow
straightening.
SECTION 2
2-3
JUNE 2013
DANIEL CRA LIQUID TURBINE METERS
Back Pressure
Back Pressure is the operating pressure measured five pipe diameters downstream of the meter. To
prevent cavitation, the minimum back pressure should be twice the pressure drop across the meter
at maximum flow plus 1.25 times the absolute vapor pressure (@100EF) of the fluid. This formula
should be used until the back pressure reaches 75-100 PSI above the vapor pressure and remain at
100 PSI for anything higher.
Piping should not allow passage of air, or vapor pockets in the flow stream. This will overspin the
rotor causing damage to the rotor and bearings.

DANIEL CRA LIQUID TURBINE METERS
JUNE 2013
Viscous Fluids
At viscosities above 20 centipoise it is recommended that Daniel Measurement engineers be
consulted to insure that the proper meter be selected for the exact application.
For low to medium viscosities, the pressure drop through the meter may be estimated by the
following formula:
ÄP
= (PD) x (µ)1/4 x (SG)3/4
Where:
µ
SG
PD
= Absolute viscosity in centispoise
= Specific gravity
= Pressure drop for water at expected flow rate (as taken from the chart)
If the kinetic viscosity (v) is given, convert to absolute viscosity by the formula:

TURBINE METER INSTRUMENTATION
Connecting the Turbine Meter to the Readout Pickup Coil
The pickup coil output is an electrical signal of varying amplitude. In most cases a Daniel
preamplifier is mounted on the turbine meter and amplifies this signal to a nominal 12 volt pulse.
A two conductor shielded cable is used to connect the pickup coil to the preamplifier, with the shield
grounded at one end. This shields the signal from electro-magnetic interference.
The amplified output is a high level signal and can be transmitted for longer distances. All Daniel
electronic instruments which operate with the turbine meters also provide filtering of the received
amplified signal, and schmitt trigger circuits to eliminate the possibility of noise interference.
SECTION 3
3-1
JUNE 2013
DANIEL CRA LIQUID TURBINE METERS
Benefits of a Preamplifier
This device shapes and amplifies the coil pulses to a level suitable for transmission up to 5,000 feet
using Belden 8770 type cable terminated into Daniel equipment. The input circuitry of all Daniel
instruments is designed to accept either the pickup coil output directly, or to accept signals which
have been boosted by the preamplifiers.
The premplifier requires 15-volt power at approximately 0.006 amp. This power is available at the
back connections of all Daniel readout instruments. The preamp required three shielded conductors
(power, signal, and common) to connect it to the instrument. For multiple-pickup meters a BiDirectional or combing preamplifier may be used. Normally the preamp is mounted in the electrical
coil enclosure on the turbine meter. On high temperature applications, however, the preamp should
be mounted far enough from the meter run so that the temperature inside the preamp enclosure does
not exceed 150EF.
Connection to a Totalizer
The “CRA” Meter may be supplied with a Totalizer. If a Totalizer is to be used with the “CRA”
Meter, refer to the appropriate Totalizer manual for installation and connection details.

GENERAL INFORMATION
“CRA” Meter Guarantee
Daniel guarantees for a period of one year from date of shipment that all “CRA” Meters are free from
defective workmanship and material. Within this period any such products or parts will be repaired
or replaced free of charge F.O.B. our factory, provided that such products were properly installed and
not misused in any matter. The products or parts must be returned to out factory and the foregoing
conditions determined by our Engineering Department.
“CRA” Meter Packaging and Shipping
Daniel “CRA” Meters are fitted with flange protectors to seal off the inside diameter. All meters are
carefully boxed or crated for protection during delivery. In some cases, meters can be bolted into the
tubes on request, but this method is not recommended. There is an extra charge for export crating.
Servicing and Storage
Periodic servicing of the “CRA” Meter is desirable to maintain optimum measurement performance.
1.
2.
3.
4.
Keep meter clean and free from foreign matter externally and internally.
Check freedom of motor rotation.
Rotor should be free to move laterally along the shaft from thrust ball to thrust ball.
Keep pickup coil and cable connections dry, clean and in good condition.
It is not necessary to disassemble meter for cleaning during normal service conditions unless it is
suspected of malfunction or if operational service is discontinued for an extended period of time. The
method of cleaning depends on the fluid being measured. It is at the discretion of the operator to
adopt the most suitable cleaning operation, with consideration given to the materials of which the
meter and its parts are made.
Steam must not be used, nor should a higher flow rate than that stipulated for the meter be applied
during in-line cleaning processes.
To store the meter, stand it on one end flange with both end flanges and pickup coil covered to
protect against foreign matter and temperature extremes. In damp storage areas, damp-proof
packaging with silica gel desiccants is recommended.
