Sitelab SL1188 Clamp On Ultrasonic Flowmeter

The SL1188 Ultrasonic clamp on flow meters is a state-of-the-art universal transit-time flowmeter designed using SLSI technology and low voltage broadband  pulse  transmission.


The SL1188 Ultrasonic clamp on flow meters is a state-of-the-art universal transit-time flowmeter designed using SLSI technology and low voltage broadband  pulse  transmission.  While  principally  designed  for  clean  liquid  applications,  the  instrument  is  tolerant of liquids with small amounts of air bubbles or suspended solids found in most industrial environments.
The SiteLab SL1188 Flow meters is a state-of-the-art universal transit time Flow Meter for Heavy Industrial applications. Sophisticated electronics incorporating the latest developments in digital signal processing coupled with powerful ultrasonic transducers deliver highly accurate flow measurement for liquids in full pipes. While principally designed for clean liquid applications, the instrument is tolerant of liquids with a small quantity of air bubbles or suspended solids common in most industrial applications.
The SL1188 ultrasonic clamp on flow meters offers low power consumption, high reliability, and outstanding applicability at an economical price. An easy to read display and clear, user-friendly menu selections make using the instrument simple and convenient. The instrument can be configured via keypad without any additional programming devices, is packaged in a die cast IP65 housing, and is available in your choice of non-invasive clamp-on or insertion transducer configurations.




SiteLab 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 entered air bubbles, commonly found in industrial and mining applications.

The SiteLab ultrasonic flow meter is 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 set distance between the two ultrasonic sensors.
