The WUF 500 is a state-of-the-art universal transit-time Flow meter designed using SLSI technology and low voltage broadband pulse transmission. While principally designed for clean liquid application, the instrument is tolerant of liquids with small amounts of air bubbles or suspended solids found in most industrial environment.

With distintive features such as high precision, high reliability, high capability and low cost, the Flowmeter features other advantages:
1. SLSI technology designed. Less hardware component, low voltage broadband pulse transmission, low consumption power, high reliability, anti-jamming and outstanding applicability.
2. User-friendly menu designed. Parameter of pipe range, pipe material, pipe wall thickness, output signal, etc. can be conveniently entered via the windows.
U.S., British and Metric measurement units are available.
3. Daily, monthly and yearly totalized flow: Totalized flow for the last 64 days and months as well as for the last 5 years are may be viewed.
Power 0n/off function: allow the viewing of time and flow rate as power is switched on and off 64 times. Also, the Flowmeter has manual or aotumatic amendment during offline sessions.
Self-contained signal output, open collector, frequency.
4. Parallel operation of positive, negative and net flow totalizes with scale factor (span) and 7 digit display, while the output of totalize pulse and frequency output transmitted via open collector.
