Sitelab SL1278 Portable Ultrasonic Flow Meter

SiteLab SL1278 Ultrasonic Flowmeter Ultrasonic Portable Enables the user to do flow measurement checks at many points in a flow process without the need for a permanent installation. This Universal transit-time meter features a dual-function push-button interface, ergonomic handheld design, and a beautiful 3.5-inch TFT Backlit digital display that significantly simplifies setup and data collection.

Compared with other traditional flowmeters or Flowmeter Ultrasonic, it has distinctive features such as high precision, high reliability, high capability, and low cost.

Sitelab SL1278 Advantages

TVT Technology designed
Fewer Hardware components
Low Voltage Broadband pulse transmission
low consumption power
Clear, user-friendly menu selections make the flowmeter simple and convenient to use.
Daily, Monthly, and yearly totalized flow.

Parallel operation of positive, negative, and net flow totalizes with scales factor(span)and 7 digit display, while the output of totalize pulse and frequency output are transmitted via relay and open collector.
