System components D-FL 220

Measuring heads

Two identically designed measuring heads, set for type A and type B, are used. Depending on the application data, different depth-of-penetration lengths are required, for example, from 100 to 1100 mm.

Stainless steel 1.4571 is used as probe material. The housing is made of impact-proof polyamide.

A 4 mA to 20 mA current signal is available as measured value output which measures the velocity and/or the volume flow and can be connected, for example, to a emission evaluation calculator or a recorder. Two relay contacts are available for signaling. Also available is a Modbus interface according to VDI 4201-3 for the connection of an emission evaluation calculator with digital interface. The various parameters are entered during the installation on site. The USB port is on the rear.

Purge flanges

The purge air which cools the ultra-sonic transducer and keeps it clean is supplied via purge flange (one for each measuring head). A toggle-type fastener connects the purge flange to the measuring head.

Mounting tubes with flange

Mounting tubes made of stainless steel 1.4571 or of glass-fiber reinforced plastic, adapted to the plant conditions, are available.

Purge air unit

A hose connects the two measuring heads to the purge air unit. The filtered air is used to cool the measuring heads and to keep the transducers clean.

Terminal box

Terminal box to output the data with connecting cable for the two sensors and customer terminal strip.

Software D-ESI 100

Software to assign parameters, to visualize the measured data, and to carry out AST, QAL2 and QAL3.

The D?ESI 100 can be parameterized, maintained and (when faults occur) analyzed via the USB port with the help of a PC and the associated software.

Optional:

Universal control unit D-ISC 100

The connected equipment can be operated and configured conveniently using the D-ISC 100. The display provides an immediate overview of the current measured values and the status of the measuring instruments.

Weather protection covers

Weather protection covers are available to protect the measuring heads when the measuring system is installed outdoors.

Additional options:

• Absolute pressure transducer
• Temperature transducer
