​​DuraTracker® Flowmeter ​

 A​ flowmeter like no other

Teledyne ISCO's new DuraTracker® flowmeter logs flow data with more features at a greater value than related products, especiallyDuraTracker-Left-WEB.png when multiple sensor connections and communication with a cell phone are required.​

DuraTracker is flow measurement made easy, wi​​th a durable build, low-cost, efficient operation, room to attach multiple devices and intelligent options for communicating data to the use​​r. It's a versatile flowmeter like no other and ideal for many flow applications.

DuraTracker's two-way communication works directly through a connection to a USB port using off-the-shelf cable, remotely using Bluetooth to avoid entering hard-to-reach areas or where safety is a concern, or using the available cell phone modem to alleviate site visits all together, thereby saving time and money.

Several useful features, many of them found nowhere else:

  • TIENet®: DuraTracker is built on a TIENet (Teledyne ISCO Environmental Network) platform that allows for plug-and-play sensors. With two available TIENet connectors, it can be used in applications that require measurement with single, redundant, or multiple flow measurements. By interfacing with TIENet 301 pH, DuraTracker can also be used as a pH logger.
  • Power: DuraTracker is available in two versions – with and without battery box.
    • DuraTracker without battery box can be operated using direct current from a power source or solar panel.   
    • DuraTracker with battery box has two battery compartments. Each compartment can accommodate two off-the-shelf lantern batteries or eight alkaline D cells. For low temperature applications, eight ISCO lithium thionyl chloride D cells are called for. To double the battery life to reduce site visits, an additional set of batteries can be installed in the second compartment. After depletion of batteries in the first compartment, power is automatically switched to batteries in the second compartment.
  • DuraTracker is field upgradable and repairable. The DuraTracker enclosure can be opened in the field to replace circuit boards, install a cell phone modem, or replace a SIM card.
  • For intrinsically safe applications, approved Teledyne ISCO flow sensors — TIENet 310 Ex, TIENet 350 Ex, and TIENet 360 Ex — can be installed in the non-safe area and connected using a TIENet barrier to a DuraTracker installed in a safe area.​
