Flowmasonic WUF 500 Clamp On Ultrasonic Flow Meter For Water

 Ultrasonic Water flow Meter

The Flowmasonic WUF 500 Clamp-On Ultrasonic Flow Meter 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 environments.

Features :

1. SLSI technology designed. Fewer hardware components, low voltage broadband pulse transmission, low consumption power, high reliability, anti-jamming, and outstanding applicability. With distinctive features such as high precision, high reliability, high capability, and low cost, the Flowmeter features other advantages:

2. User-friendly menu design. The 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 may be viewed. Power on/off function: allows the viewing of time and flow rate as power is switched on and off 64 times. Also, the Flowmeter has a manual or automatic 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 totalized pulse and frequency output is transmitted via the open collector.
