ITABAR Flow Sensor Type FTMD Operating manual
1. Product Description
When installed properly, the ITABAR sensor offers
an array of advantages over other measurement
systems with respect to its accuracy, pressure loss,
and installation. The following guide line is
designed to help you with the sensor installation
and operation.
The ITABAR flow sensor is so constructed, that all
cross sections have a min. diameter of 8 mm
(Fig.1). So it´s guarantee, that condensate with a
max drop diameter of 6,5 mm can flow back from
the condensate pots into the flow sensor. So it can
continuous a change of condition of aggregation
from liquid to steam. (Prandl,L. "Führer durch
Strömungslehre).

2. General
FTMD Flo-Tap Sensors are designed for
installation under pressure in lines with static
pressure up to 16bar and to 300°C with graphite
packing gland.
All items for installation are provided with FloTaps except for drilling and welding equipment.
These instructions call for the use of a Mueller
DH-5 drilling machine (or equivalent), which is
rated for 80 bar at 35°C with a maximum temperature of 120°C. This machine will handle the
installation under pressure of the Flo-Tap Sensor
FTMD 25 under its full rated pressure of 70 bar.
Other drilling machines are available.
The sensor material and the mounting hardware can
be specially selected to accommodate special
operating conditions (e.g. corrosive media).
3. Pre-Installation Checks
Before installation, make sure that all of the following parts are included in the sensor kit.
• ITABAR Sensor, type FTMD
• condensate pots flanged
• Weld socket
• gaskets for condensate pots flanged
• Sensor end support, with sealing plug
(for FTMD 26 only)
• Instrument valve assembly (if ordered)
Compare the specifications at the type identification plate of the sensor with your order form.
The identification plate contains the following information:
– Serial number
– Type name
– Pipe inside diameter
– TAG number (Measuring location number if furnished)
– Material
Attention!
Make sure that the pipe inside diameter given on
the identification plate matches your pipe diameter.

5. General Installation Notes
In order to obtain optimal measurement results,
follow the notes concerning the installation of the
ITABAR Sensor given below.
5.1 Determination of Pipe Arrangement
For design reasons, the pipe arrangement at the
installation location has to be known before the
sensor is manufactured.
For horizontal pipe arrangements the instrument
connections are placed in-line with the flow
direction (see Figure 2).
For vertical pipe arrangements, the instrument
connections for the measurement of the differential
pressure are arranged at an angle of 90° to the flow
direction (see Figure 3).
