2Product Description
This section covers the reference and specification data, as well as ordering information.
2.1 Introduction
The Tek-DP 1650A DProbar Multiport Self-Averaging Flow Meter functions as an obstruction that
changes the cross-section of the flow of the liquid in the pipe or conduit. In a differential pressure
flow meter, as the liquid passes through the obstruction, its potential energy is converted into
kinetic energy. The velocity of the liquid increases and is accompanied by a simultaneous decrease
in the pressure. When the liquid exits the obstruction, the velocity decreases, and the pressure
increases again. These pressure drops generated across the obstacle are proportional to the flow
rate square and calculated using Bernoulli's equation.
2.2 Measuring Principle
While the Tek-DP 1650A DProbar measures the pressure of a liquid at a single point, the more
modern averaging Tek-DP 1650A DProbar measures the average pressure by taking sample values
at different points in the pipe. It is inserted directly into the pipe and is perpendicular to the
direction of flow. The side of the tube facing the flow of the liquid consists of several impact
pressure ports while the opposite side of the tube may have a single or multiple static pressure
ports. These ports are connected together to a secondary device such as a differential pressure
transmitter.
When the liquid comes in contact with the tube, the kinetic energy of the liquid is converted into
potential energy and velocity is reduced to zero. The pressure now measured at the upstream
ports is called the total impact pressure, which is the sum of the static pressure and the dynamic

5
pressure of the liquid. The impact pressure is directly proportional to the flow rate of the liquid.
As the liquid flows around the Tek-DP 1650A DProbar, the static pressure ports measure the
decrease in pressure downstream of the flow. These pressure differentials are then averaged to
determine the flow rate of the liquid using the following formulas:
To calculate the volumetric flow rate:
QA= N * K * D2* Faa * (√DP/GF)(For liquids)
QA= N * K * D2* Faa *(√DP/ρF)(For gases)
To calculate the mass flow rate:
QMASS = N * K * D2* Ya* Faa * √(P*DP) /T (For gases and steam)

Improper installation has the potential to cause injury and to damage instrument.
Periodically inspect the power cables, transducer cables, cable glands and the enclosure for
signs of damage. Inspect transducer installation and mounting hardware for loose
connections.
3.1 Selection of Installation of Locations
•Correct location of the Fluid Bar-in the pipeline is important because disturbance in flow
produced by the pipe layout may affect the accuracy of measurement. The following
standard practices should be reviewed before selecting a mounting location.
•Straight Run Requirements
The minimum straight length requirement between various fittings located upstream of
Fluid Bar are given in Table 1. Use of recommended straight pipe lengths of uniform
diameter ensures that the flow measurement will be made with fully developed
characteristics.
Included gate, globe, & other throttling valves that are partially opened. If the valve is full
open, use valves shown for 4 & 5. Values shown are the recommended spacing in terms of
internal diameters for normal industrial metering requirements. For laboratory of high
accuracy work, add 25% to above values.
•Flow Conditioners
Flow conditioner may be used to reduce the length of straight pipe required in many cases.
Any flow conditioner used shall be installed in the upstream straight length between the
Fluid Bar & disturbance or fittings closest to the Fluid Bar. Unless it can be verified that the
flow conditions at the inlet of Fluid Bar shall confirm fully developed profile & are free from
swirl.

3.2 Installation Procedure
1. Verify that the line pressure & temperature are within the rated limits for respective models.
2. Grind off paint or other coatings from the pipe in the area where the Flow-Tap is to be
installed. (Except for steam applications, Flow-Tap may be installed at any angle around the
pipe.)
3. Drill or bum a 35.0 mm diameter hole in the pipe &for Type FTM-76 & FrH-76 drill or burn. a
35.0 rim diameter hole on the opposite side of the pipe for end support.
4. Tack weld the 40 NB weld coupling to the pipe. The coupling must be aligned perpendicular to
the pipe axis & square to its plane. For Type FTM-76 & FTH-76, tack weld the end support on
the opposite side of the weld coupling. Ensure the end support is aligned perpendicular to the
pipe axis & in line with the weld coupling.
5. Install the Flow-Tap unit-isolating valve on the process connection. Verify that the valve is in
the fully open position, & that the stem is in line with the pipe to ensure clearance for the
insert-retract rods.
6. Install the Flow-T ap cage nipple into the unit-isolating valve.
7. Inspect Flow-Tap assembly to ensure that the insert-retract mechanism is fully retracted.
8. Install the Flow-Tap assembly on the cage nipple. When tight, the flow arrow on the top of the
Flow-Tap head must point in the direction of flow.
9. Initiate sensor insertion by rotating the drive nuts clockwise as viewed from the top, using the
ratchet wrench supplied with the unit. The nuts must be tightened alternately, about two
turns at a time to prevent binding resulting from unequal loading. Continue this procedure
until the sensor contacts the opposite side of the pipe or end support.

10. Connect instrument lines to the instrument valves 8 to the appropriate meter, recorder,
transmitter w controller.
11. Retract the sensor by rotating the drive nuts counter-clockwise as viewed from the top. The
nuts must be turned alternately, about two turns at a time, to prevent binding resulting from
unequal loading. Continue this procedure until the sensor is fully retracted.
NOTE
If flow rate higher than 66 lb.ft/sec (90Nm/s) or pipe size larger than 8”(DN400), will require
19mm diameter probe, mounted in 1” ball valve and 1” socket and 22mm hole
4Electrical Connection
This section covers the all electrical connection requirement. Electrical connection of the device
must be carried out by trained, qualified specialists authorized to perform such work by the
installation site.
WARNING
•Connect all electrical cables when the power is switched off. If the device does not
have switch-off elements, then, overcurrent protection devices, lightning protection
and/or energy isolating devices must be provided by the customer.
•The device must be grounded to a spot in accordance with regulations in order to
protect personnel against electric shocks.
NOTE
•When using the measuring device in hazardous areas, installation must comply with
the corresponding national standards and regulations and the Safety Instructions or
Installation or Control Drawings.

4.1 Grounding of Measuring Device
5Troubleshooting
Fluid Bar operates on natural scientific principles. No moving parts are used in the design, & wear
has negligible effect on accuracy. If installed correctly, Fluid Bar will provide a correct flow indication
if there is a flow in the pipe. To solve a discrepancy, interpretation of the Fluid Bar signal & other
components of the flow system should be examined closely.
Fluid Bar installation - Ensure that the Fluid Bar flow arrow is pointing directly downstream. The
Fluid bar accuracy will be influenced by installation misalignment. To ensure meeting stated
accuracy, alignment must be within limits shown below.
Pipe size - The Fluid Bar may have been designed for a
different pipe size than that in which it is being used.
Measure pipes the ID & compare with the size printed
on identification tag attached to the Fluid Bar.
Insufficient straight run - If the Fluid Bar is installed in
less than recommended straight uniform pipe length,
accuracy may be affected. Refer straight run
requirements
Calculation - The calculation for a particular Fluid Bar
may be in error. Recheck the calculation or graph used
for conversion. Changes in operating temperature or
pressure are critical for air, gas, or steam applications.
Recheck actual operating temperature & pressure
compared to values used in the calculation.
