SiteLab SL1188 Clamp On Ultrasonic Flow Meter


Clamp-on ultrasonic flow meter sl1188 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.

Clamp-on ultrasonic flow meter  SiteLab SL1188 is a state-of-the-art universal transit-time Flow Meter for Heavy Industrial applications. Sophisticated electronics incorporating, the latest developments in a digital signal processor coupled. With powerful ultrasonic transducers deliver highly accurate flow measurement for liquids in full pipes.

Principally, an instrument designed for clean liquid applications. The instrument is tolerant of liquids with little air bubbles or suspended solids common in most industrial applications. Clamp-on ultrasonic flow meter SL1188 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 feature a self-contained 4-20 mA current loop signal output for instantaneous flow. And there are has two independent temperature inputs for thermal energy monitoring.
