Description

Sitelab SL1188 Clamp On Ultrasonic Flowmeter

Sitelab SL1188 Clamp On Ultrasonic Flowmeter is a state-of-the-art transit time ultrasonic flowmeter. Designed using the latest digital technology and low-voltage broadband pulse transmission.

While principally designed for full-pipe clean liquid applications. The instrument is tolerant of liquids with small amounts of air bubbles or suspended solids found in most industrial environments.

Comparing with other traditional flowmeter or ultrasonic flowmeter, it has distinctive features such as high precision, high reliability, high capability and low cost.

Sitelab SL1188 Features

TVT technology designed.
Less hardware components, low voltage broadband pulse transmission, low consumption power.
Clear, user-friendly menu selections make flowmeter simple and convenient to use.
Daily, monthly and yearly totalized flow.
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 are transmitted via relay and open collector.
