ULTRAFLOW 150 GAS FLOW AND TEMPERATURE MONITOR
2.0 SYSTEM OVERVIEW
This manual describes the installation, operation, calibration and routine
maintenance of the Teledyne Monitor Labs Ultraflow 150
Ultrasonic
Stack Flow Measurement System.
2.1 SYSTEM DESCRIPTION, STANDARD EQUIPMENT
The Ultraflow 150 system consists of the following standard equipment.
Transducer Interface Enclosure (TIE)
Purge Nozzle Assemblies
Protective Purge Air System (Single)
Enhanced Remote Panel (ERP)
(Not supplied with a 560DI, see section 3.5)
As shown on the Ultraflow 150 Installation Drawings, the first three above
are located on the stack. The Enhanced Remote Panel Assembly is
typically located in the plant Control Room or CEMS Shelter.
2.1.1 Transducer Interface Enclosure (TIE)
The Transducer Interface Enclosure Assembly contains sophisticated
sampling electronics that control the transmit and receive signals from the
transducers and calculates the flow velocity, flow volume and
temperature. It also provides power for the purge fail sensors. These
measurement data are transmitted to the Enhanced Remote Panel via a
commercial network communication protocol.
Each TIE is capable of controlling and performing analysis of up to two
pairs of Purge Nozzle Assemblies.
2.1.2 Purge Nozzle Assemblies
There are two Purge Nozzle Assemblies located on opposite sides of the
stack or duct. Each houses an ultrasonic transducer and is designed to
conduct the protective purge air around the transducer to prevent
contamination from the effluent gas stream. The Purge Nozzles are
constructed using Teflon, stainless steel, and other corrosion resistant
materials to provide a long service life. The actual transducer element is
housed in the Transducer Housing Subassembly and is located near the
end of the Purge Nozzle Nosepiece.
