Product Description
TF series turbine flow meters have the features: high accuracy, good repeatability, convenient
installation/maintenance, simple structure etc.

Liquid flows through the turbine housing causing an internal rotor to spin. As the rotor spins, an electrical signal
is generated in the pickup coil. This signal is converted into engineering units (liters, cubic meters, gallons etc.)
on the local display where is applicable. Optional accessory modules can be used to export the signal to other
equipment.

Upon receipt, examine your meter for visible damage. The turbine is a precision measuring instrument and
should be handled carefully. Remove the protective plugs and caps for a thorough inspection. If any items are
damaged or missing, contact.

Make the turbine flow model meets your specific needs. For your future reference, it might be useful to record
this information on nameplate in the manual in case it becomes unreadable on the turbine. Refer to the
nameplate for your customized product’s specification.

4.0 CAUTIONS FOR INSTALLATION

Mounting Positions
Turbine flow meters should be installed at the place in compliance with the requirements below:
⚫ Easy maintenance
⚫ No vibration
⚫ No electromagnetic interface
⚫ Away from heat source

Mounting Orientation
All turbine flow meters are designed to mea flow in only one direction. The direction is indicated by the arrow on
the body.

Required Lengths of Straight Runs

Flow altering device such as elbows, valves and reducers can affect accuracy. See diagram 1 for typical flow
meter system installation.

Diagram 1. Typical Flow Meter System Installation

The recommended guidelines are given to enhance accuracy and maximize performance. Distance given here
are minimum requirements; double them for desired straight pipe lengths.

⚫ Upstream: allow a minimum straight pipe length at least 10 times the internal diameter of the pipe. For
example, with the 50mm pipe, there should be 500mm of straight pipe immediately upstream. Desired
upstream straight pipe length is 1000mm.
⚫ Downstream: allow a minimum straight pipe length at least 5 times the internal diameter of the pipe. For
example, with the 50mm pipe, there should be 250mm of straight pipe immediately upstream. Desired
upstream straight pipe length is 500mm.

5
TF Turbine Flowmeter May 2015

See diagram 2 for straight pipe length requirement when there is altering device.

Diagram 2. Number of Pipe Dia meter (D=Diameter)

Warning: Precaution for direct sunshine and rain when the meter is installed outside.

Anti-Cavitation
Cavitation can be caused by entrained air, and it can seriously damage the rotor on a turbine flow meter. An
amount higher than about 100 mg/l of entrained air or gas can produce error. In addition, cavitation can be
caused by too little backpres on the flow meter. For turbine flow meters, you should provide a backpres
(downstream pres) of at least 1.25 times the vapor pres, plus 2 times the pres drop through the flow meter. See
formula 1.
Formula 1: Pb ≥ 1.25×Pv + 2× (Pin – Pout)
In formula 1: (Pb: Back pres; Pv: Vapor Pres; Pin: Inlet Pres; Pout: Outlet Pres)

Create backpres by installing a control valve on the downstream side of the meter at the proper distance
detailed above.

Special Notice

⚫ Foreign material in the liquid being mead can clog the meter’s rotor and adversely affect accuracy. If this
problem is anticipated or experienced, install strains to filter impurities from incoming liquids.

⚫ To ensure accurate measurement, drain all air from the system before use.

⚫ When the meter contains removable coverplates. Leave the coverplate installed unless accessory modules
specify removal. Don’t remove the coverplates when the meter is powered, or electrical shock and
explosion hazard can be caused.

TF Turbine Flowmeter May 2015

Thread Connections
1. To protect against leakage, seal all threads with an appropriate sealing compound. Make the sealing
compound not intrude into the flow path.
2. Make the arrow on the outlet point to the direction of the flow.
3. Tighten the turbine onto the fittings. Use a wrench only on wrench flats.

Flange Connections
For standard product, the flange follows GB/T 9119-2000 (ISO 7005-1) RF (Raised Face).
Note: flange can be customized as your requirement.
Use a gasket between the meter flange and mating flange. Determine the material of the gasket based on the
operating conditions and type of fluid.
Note: Do not over tighten the flange bolts. This may cause the gasket to be compressed into the flow stream and
may decrease the accuracy of the meter.
