SiteLab Ultrasonic Flow Meter is a registered US trademark by flow measurement professionals with more than 37 years of experience in flow measurement and flow standards, 34 years of which have been in the ultrasonic flow measurement field. We are pioneers in the ultrasonic flow measurement industry and possess many years of experience valuable to our customers. Primarily designed for clean liquid applications, the SiteLab will handle liquids with small amounts of suspended solids or entrained air bubbles, commonly found in industrial and mining applications.
The SiteLab units are user-friendly and easily set up in just a few minutes by means of an interactive display, whereby various parameters, such as the type of fluid to be measured, pipe size, thickness of the pipe wall, and material of construction, are all entered into the unit and the unit then computes the data in order to give the setting distance between the two ultrasonic sensors.
About SL 1278
SL 1278 Portable Ultrasonic Flowmeter 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 beautiful 3.5in TFT backlit digital display that significantly simplifies setup
and data collection.
Compared with other traditional flowmeters or ultrasonic flowmeters, it has distinctive features such as high precision, high reliability, high capability, and low cost, the flowmeter features other advantages: TVT technology designed. Less hardware components, low voltage broadband pulse transmission, and 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 scale factor (span) and 7-digit display, while the output of totalized pulse and frequency output are transmitted via relay and open collector.

Installation Site Selection
- When selecting a measurement site, it is important to select an area where the fluid flow profile is fully developed to guarantee a highly accurate measurement. Use the following guidelines to select a proper installation site
- Choose a section of pipe that is always full of liquid, such as a vertical pipe with flow in the upward direction or a full horizontal pipe
- Ensure enough straight pipe lengths at least equal to the figure shown below for the upstream and downstream transducers installation
- Ensure that the pipe surface temperature at the measuring point is within the transducer temperature limits.
- Consider the inside condition of the pipe carefully. If possible, select a section of pipe where the inside is free of excessive corrosion or scaling.
