SL1188 Ultrasonic flow meter
Clamp On Installation Flow Meters

The SL1188 ultrasonic flowmeter can be used to measure flow and provide water quality data acquisition at the same time. Data for flow, pressure, turbidity, residual chlorine and pH can be collected at the same time. The system is simple, reliable and convenient to use.

The SiteLab SL1188 Flow meters is a state-of-the-art universal transit-time FlowMeter 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.

Use GPRS wireless communications for wide coverage and reliable communications.  There is no need to install outdoor antennas which greatly shortens project installation and start up time and reduces total project cost greatly.

The SL1188 Ultrasonic clamp on flow meters is a state-of-the-art universal transit-time flow meter 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 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.

The SL1188 ultrasonic flow meters features a self-contained 4-20 mA current loop signal output for instantaneous flow, as well as two independent temperature inputs for thermal energy monitoring. The instrument also features a 7 digit alpha- numeric display, parallel operation of positive, negative and net flow totalizers (with user-selectable scale factors) and configurable pulse and frequency outputs (transmitted via relay and open collector) for totalized flow. As standard it incorporates a 1G SD Card for data logging and is supplied with the software to download stored data to your PC.
