SL1188 Industrial Transit Time Flowmeter by SiteLab

SL1188 Industrial Transit Time Flowmeter from SiteLabThe SL1188 from SiteLab Industrial Transit Time Flowmeter incorporates the latest developments in digital signal processing to deliver highly accurate and repeatable flow measurement for a wide variety of liquids and pipe sizes.

It  has sophisticated electronics coupled with powerful ultrasonic transducers to make this universal transit-time flow meter the top choice of industry leaders.

An easy to read display and clear, user-friendly menu selections make using the instrument simple and convenient. Quick key buttons for flow, totalized flow, velocity, fluid, signal and diagnostics make set up and data collection even easier. High temperature clamp-on and insertion options are available, making the unit more flexible. PCA’s inside the meter have been modularized, enabling field swap out for repairs or upgrades.

  • Dedicated flowmeter with clamp on tranducers
  • Wetted tranducers optional
  • Signal processed by 400k gate array to reach ultra fine time resolution
  • SD Card for data logging
  • RS485, 4-20mA

The SL1188 also features a large alpha-numeric display, parallel operation of positive, negative and net flow totalizers (with user selectable scale factors), and configurable pulse, analog and frequency outputs. SD data logging capability is included and energy monitoring is fully supported.

It offers low power consumption and high reliability. The instrument can be configured via keypad without any additional programming devices. It is packaged in a die cast NEMA 4X (IP65) housing, and is available in your choice of non-invasive clamp-on or insertion transducer configurations.
