Area Velocity Module

The 2150 Flow Module uses continuous wave Doppler technology to measure mean velocity. The sensor transmits a continuous ultrasonic wave, then measures the frequency shift of returned echoes reflected by air bubbles or particles in the flow.

The 2150’s “smart” area velocity probe is built on digital electronics, so the analog level is digitized in the sensor itself to overcome electromagnetic interference. The probe is also factory-calibrated for 10-foot (3 meter) span at different temperatures. This built-in calibration eliminates drift in the level signal, providing long-term level stability that reduces recalibration frequency and completely eliminates span recalibration.

In field use, the 2150 is typically powered either by two alkaline, or Teledyne ISCO Rechargeable Lead-acid batteries, within a 2191 Battery Module. Highly efficient power management extends battery life up to 15 months at 15-minute data storage intervals. Other power options (including solar) are available.

2160 LaserFlow® - Teledyne ISCO

The 2160 LaserFlow Module uses non-contact Laser Doppler Velocity technology and non-contact Ultrasonic Level technology to remotely measure open-channel flow. The sensor has advanced technology to measure velocity with a laser beam at single or multiple points below the surface of the wastewater stream.The LaserFlow is ideal for a broad range of wastewater monitoring applications.During submerged conditions, flow measurement continues without interruption with optional Doppler Ultrasonic Area Velocity technology.In field use, the 2160 is typically powered either by two alkaline, or Teledyne ISCO Rechargeable Lead-acid batteries, within a 2191 Battery Module.

Ultrasonic Flow Module

2110 - Teledyne ISCO

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.

CDMA Cellular Modem Module

2103Ci - Teledyne ISCO

This cellular modem module is designed to push Teledyne ISCO 2100 Series flowmeter data to a remote Flowlink® database. Data can also be downloaded from the server using an internet connection. The 2103Ci modem module uses Serial Over Internet Protocol (SOIP), so a landline modem is not required. This ability virtually eliminates the need for routine site visits, time-consuming (and potentially dangerous) confined space entry, as well as costly installation of land lines.

GSM/GPRS Cellular Modem Module

2103LTE - Teledyne ISCO

This cellular modem module is designed to push Teledyne ISCO 2100 Series flowmeter data to a remote Flowlink® database. It virtually eliminates the need for recurring site visits, time-consuming (and potentially dangerous) confined space entry, as well as costly installation of land lines. The 2103LTE is compatible with user-subscribed GSM digital cell one service (such as AT&T and T-Mobile). GSM subscription parameters are contained on a SIM card that you install in the modem. Service parameters – or provider – may be changed by simply replacing the SIM card. The 2103LTE stacks together with up to three other Teledyne ISCO 2100 Series flow modules of your choice, giving you a compact, integrated system for open channel flow data collection and management.

Network Interface Module

2105 LTE - Teledyne ISCO

The 2105 Interface Module is a powerful solution for environmental monitoring professionals to interface different monitoring and recording instruments. The 2105 will monitor the recorded data and take intelligent actions, such as sampler enabling, pacing, and/or alarm generation, based on user-specified conditions. Its unique flexibility allows connection to several devices at the same time. 2100 Series Flow Modules, 6712 Samplers, and Teledyne ISCO Rain Gauges are directly compatible. It can also be used with non-Teledyne ISCO instruments that have SDI-12 or Modbus output. Additional input options (4-20 mA, etc.) are possible using readily-available aftermarket converters. An optional built-in cell phone modem allows remote access to data that has been stored within the 2105, and can fed to a central server via the Internet. Teledyne ISCO’s modular design allows the 2105 to be stacked with other 2100 Series flow, communication, interface, or display modules.
