 Overview

​2110 Ultrasonic Flow Module

For redundant level measurement with 2150, or standalone ultrasonic level/flow measurement


The 2110 Ultrasonic Module provides accurate non-contact liquid level measurement, using built-in software to calculate flow in weirs, flumes and streams. When used in conjunction with Teledyne ISCO’s Flowlink® data handling software, that information can be managed and used in a wide variety of ways.

With the 2110, an ultrasonic sensor mounted above the flow stream transmits sound waves, which are reflected by the liquid surface. The elapsed time between transmitted and returned signals determines the liquid level.

The device then calculates flow rate, using the liquid level reading and a built-in conversion for the specified primary device or natural stream boundaries.

It can also be used for redundant level measurement to complement Teledyne ISCO’s 2150 Area Velocity Flow Module.

Standard Features

  • Digital communication between sensor and flow module makes it immune to RF interference.
  • Sensor deflector plate resists condensation.
  • Minimal deadband in level measurement.
  • Chemically resistant (PVDF) sensor package.
  • Modular, stackable design snaps together with other 2100 modules to quickly create application-optimized configurations.
  • Software features:
    • Variable data storage rates can automatically be switched when conditions vary
    • Communicates at 38.4k baud for speedy setup and data retrieval.
    • Easily upgradeable. New operating software can be downloaded into non-volatile "flash" memory, without affecting your stored program or data.
    • Rollover memory with variable rate data storage lets you change the data storage interval when programmed conditions occur.
    • Secure data storage. All data are continuously stored in “flash” memory to protect against loss in case of power failure. 
    • Records and stores input voltage information to let you know when to change batteries.

Applications

  • CSO, SSO, I&I, cMOM, SSEs, Sewer flow monitoring.
  • Open-channel flow measurement with or without primary devices.
  • Redundant level measurement in combination with Teledyne ISCO 2150 Area Velocity Flow Modules, or other AV systems.
  • Non-contact flow measurement in streams containing harsh chemicals, grease, or suspended solids.

Options and Accessories

  • Direct connect, modem, or wireless communication options let you choose the best data retrieval method for any job.
  • Bracket, suspension, or insertion mounting of ultrasonic sensor makes setup quick and flexible.
  • AC power adapter for fixed sites.
