Pipe Components; Flowmeter Sensor - ABB Sensyflow FMT200-D Operating Instruction

Design and function
2.1

Pipe components

Pipe components for nominal diameters 1 ... 3" are available in various designs. In addition it is
possible to integrate the flowmeter sensor directly into pipes of DN 100 ... DN 250 (4 ... 6") or
into pipes with non-circular cross-sections using a weld-on adapter.
The pipe components and weld-on adapters guarantee the defined installation of the transducer
in the pipeline. Moreover, they allow simple removal and installation of the transducer for
inspection and/or cleaning. By closing the pipe component with a blind flange, it is possible to
use the measuring section even without installed transducer.
The versions available as standard - depending on the respective nominal diameter and the
desired adaptation - are shown in chapter 8 Specifications.
2.2

Flowmeter sensor

The flowmeter sensor designed as a plug-in unit contains, besides the sensor unit, the sealed-in
transmitter circuitry accommodated in the sensor head. The circuitry mainly consists of the
differential temperature control unit for the sensor elements, a memory for all parameters that
are specific to the measuring point, a connector for the LCI adapter, and the computing power
for creating flow-dependent data records.
In addition, a flow-linearized analog signal of 0/4...20 mA (electrically isolated) is directly
provided. No special supply/evaluation device is required. The flowmeter sensor is installed in
the pipe component as a plug-in unit with a centering pin in a defined manner. See chapter 8
Specifications.
