Description
By calculating velocity ratios between two or more ultrasonic paths, the simply constructed model FLC-UFL ultrasonic flow meter provides reliable gas flow measurement. Additional measured, such as sound, signal-to-noise ratio or signal strength, are available for condition monitoring. For applications requiring integrated volume conversion, pressure and temperature sensors can be connected.
The flow meters are certified in accordance with ATEX/IECEx and cQPSus intrinsically safe for zone 0. The instrument allows for easy and quick installation and commissioning since no special provisions for wiring and case are required.
The patented broadband continuous-wave technology ensures low-noise and reliable measurements, even in the most demanding applications. The epoxy-coated aluminium-alloy electronics case has an ingress protection of IP66 and NEMA 4X for outdoor use.
For offshore applications, a version in stainless steel is available. The transducers are completely encapsulated with titanium grade 2 and designed for harsh conditions and corrosive media.
The model FLC-UFL provides comprehensive flow and diagnostic information on the local display and remotely via a PC software interface, enabling real-time data logging and condition monitoring.
The display shows an overview of the instrument's set parameters, such as units, pipe size and ultrasonic path configuration. Traceability information such as firmware version, checksums and serial numbers are also displayed.
The model FLC-UFL is supplied, as standard, with a pulse/frequency output and a USB port for commissioning and service. Via option boards, an isolated RS485 and two additional isolated pulse/frequency outputs as well as a 4 ... 20 mA/HART® output can be provided.
