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 4x4 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
