2.1 Introduction
Tek-Vor 1300C Vortex Flowmeter (also called a Vortex Shedding Flowmeter) is a versatile
instrument that calculates the mass flow, volumetric flow rate, temperature, and pressure and
density of any liquid, gas, or steam through a pipeline.
2.2 Measuring Principle
This flowmeter operates on the principle of Karman Vortex Street, any medium passing through
the pipeline flows around the bluff body and sheds a series of alternating vortices on each side
of the body. This phenomenon is referred to as Vortex Shedding. These vortices shed
downstream of the bluff body and dissipate as they flow further. This pattern of vortices is called
a Karman Vortex Street (also called a Von Karman Vortex Street).
A Vortex Flowmeter primarily consists of a bluff body, a sensor assembly, and a transmitter. A
bluff body or a shedder is nothing but a non-streamlined object or a barrier placed
perpendicular to the axis of the pipeline, around which the medium flows.
Calculation of volumetric flow rate
The frequency of the vortices, i.e., the number of vortices shed per second, is directly
proportionate to the velocity of the medium. This Vortex Shedding Frequency is used to
calculate the mass flow as well as the volume flow. The sensor assembly records the pressure
and velocity oscillations generated on each side of the bluff body by the vortices and generate
a digital linear output signal. The Vortex Shedding Frequency is calculated using the following
formula:
The flowmeter should not be installed at a location where it could have strong vibration. If the
mounting pipeline could have heavy vibration, the pipeline should be held steady by some
support racks.
All screws and bolts should be tightened
Make sure there is no leakage point on the connection
The process pressure should not be higher than the flowmeter’s rated pressure
This section covers instructions on installation and commissioning. Installation of the device must
be carried out by trained; qualified specialists authorized to perform such works.
CAUTION
• When removing the instrument from hazardous processes, avoid direct
contact with the fluid and the meter
• All installation must comply with local installation requirements and local
electrical code
3.1 General Notes on Installation
• Ambient Temperature
Please avoid installing the flowmeter at a location where temperature could dramatically
change. If the meter is under heavy heat radiation, please implement effective heat insulation
and venting method.
• Atmosphere
Please do not install the flowmeter at a location where the atmosphere contains a high level
of corrosive substance. If the meter cannot be installed at a better location, please make sure
there is enough venting.
•
CAUTION
•

• Lifting equipment for flowmeter should confirm to safety provision.
3.3 Installation Condition
NOTE
When the upstream pipeline is a T-type and the flowmeter and the valve
downstream of the meter is shut, fluid will flow toward pipe B, however the meter
may still show a reading, as it may be detecting a pulsating pressure. In this case,
please close the upstream valve V1.

4.1 Terminal Board
The Tek-Vor 1300C has two different terminal boards; a 5-terminal board for standard models
and a 12-terminal board for multi-variable models.
On the above boards, V+ and V- are for power. is the pulse output terminal. A, B are “+” and “-” terminals for RS485 Modbus communication. I+ and I- are “+” and “–“ for 3-wire or 4-wire 4
to 20 mA. RT1, RT2, RT3 are for separate RTD. P+, P- are for pressure transmitters. The Tek- Vor
1300C multi–variable version has a built in RTD and pressure sensor, so there is no requirement
to wire for temperature or pressure compensation.
4.2 Wiring for a 5-Terminal Board
4.2.1 Wiring for a 3-Wire Pulse Output
A 3-wire pulse output requires a power source of 13.5 to 42VDC. VFM uses a current pulse
output with 50% duty ratio. If the pulse-receiving instrument requires a voltage pulse, add a
resistor between “” and “V-”; the resistance should be within 500 ohms to 1000 ohms, and
the power consumption should be no less than 0.5W.
*Note:- Pulse Output: Active (Pulse, V-), 4-20 mA output:Passive (I+, I-),
Remarks for Pulse Output: With/Without 250 ohms resistor across Pulse &V- terminals,
Remarks for 4-20 mA output: External 24VDC to I+.connect PLC/Multimeter between I- and -Ve ofpower supply, Diagrams for Pulse: Active, Diagrams for 4-20mA:
When there is no temperature and pressure compensation and the power source is 24VDC,
the maximum load for 4 to 20mA analog is 500 ohms. When there is temperature and pressure
compensation and the power source is 24VDC, the maximum load for 4 to 20mA analog is 400
ohms. When using a HART communicator, add a 250 ohms load resistor.
