Clamp On Ultrasonic Flow Meter
Transit time Ultrasonic Flow Meter

SL1168 Ultrasonic Flow meter uses the latest digital technology and low-voltage broadband pulse transmission. The instrument is tolerant of liquids with small amounts of air bubbles or suspended solids found  in most industrial  environments.  With distinctive features such as high accuracy, high reliability,  the  MPU  in the instrument provides unique digital signal processing and a relevant test programs. 
This flow meter provides long-term no-drift measurements and sorts the operating software to adjust parameters according to changing conditions.

The SL1168 ultrasonic flow meter delivers highly accurate and repeatable flow measurement for water at a significantly reduced cost. Incorporating the core technologies of the SL1188 Industrial meter, the design of the SL1168 universal transit-time flow meter is focused on those features that optimize the measurement of water flows in irrigation, swimming pool, clean waste discharge, building services and other water applications.

Ideal for pipes up to 48” (1200 mm) in diameter, the SL1168 promises accuracy to +/-1.0% of reading,
repeatability of +/-0.3% of reading and a temperature range of 0 C to 60 C. High temperature sensors to 150 C are available as an option.
The SL1168 offers low power consumption and high reliability at a very competitive price. An easy to read display and clear, user-friendly menu selections make using the instrument simple and convenient. It can be configured via a 4×4 keypad without additional programming devices and features a 20 x 2 digit alpha-numeric display.

The SL1168 features a programmable frequency output, a relay output and a programmable current loop output. RS 232 and MODBUS RTU are standard, while RS 485 is optional.
The SL1688 is packaged in a lightweight polycarbonate IP65 housing and includes clamp-on encapsulated IP 68 sensors that are easy to install and require no pipe cutting, thereby reducing installation and labor costs. Where pipes are found to be acoustically dead wetted sensors are available. installasi


  • Weather-proof robust housing materials: corrosion -resistant, rust-resistant, freeze resistant.
  • Designed to be user friendly ,easy to operate, installations within just20 min .
  • Suitable for measurement in many different working conditions
  • Compact design, easy to installasi .

 SL1168 Ultrasonic Flow meter targets irrigation applications and features compact  design, easy operations, high dynamic response with economical price; also,  the  meter features intelligent  control, fault alarms and self diagnostics, which highly increases the working efficiency .

SL1168Ultrasonic Flow meter uses advanced framework configuration with compact design. It consists of five main parts:  enclosure, LCD di splay, power supply board, PCB main board and operating panel. This configuration increases the reliability of the product and decreases the cost and maintenance as well. The convenient digital menu operation can easily be used to set up the pipe size, pipe material, pipe thickness, fluid type, output signal  and other parameters. 

SL1168 is equipped clamp-on transducers made with SiteLab patented technology, which is suitable for metal, PVC and other pipe materials, or lined pipe. The transducers use robust material with the high performance piezo electric crystals with high accuracy and good performance during measurement.  At the same time, it’s easy and convenient to install. Users only need to fix it on the pipe  with the pipe straps, and setup the transducer spacing according to the prompt  calculation of the meter. It only  takes minutes to complete
