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 Isco Rechargeable Lead-acid batteries, within a 2191 Battery Module. Other power options (including solar) are available.

2160 LaserFlow™ 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 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.

• Easy to upgrade. New operating software can be downloaded into non-volatile flash memory, without affecting stored program and data. 
• Records and stores input voltage and temperature data. 
• Variable rate data storage lets you change the data storage interval when programmed conditions occur. This feature assures maximum information about an exceptional event – such as an overflow – while conserving power and data capacity during normal conditions. 
• 38,400 bps communication provides speedy setup and data retrieval.

Applications

• Portable and permanent-site AV flow monitoring for inflow and infiltration, capacity assessment, sewer overflow, and sewer studies.

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 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 Isco’s 2150 Area Velocity Flow Module.

Data communication and storage

This cellular modem module is designed to push Isco 2100 Series flow meter 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.

The 2103Ci can automatically send data via the internet to a designated server running Isco Flowlink Pro software, using economical 1xRTT data transmission. The user-specified primary data transmission interval (from 5 minutes to 24 hours) can automatically change to a secondary interval when specific conditions occur at the monitoring site. An Oracle® or Microsoft® SQL database on your server is required to use this feature. Contact the factory for additional information.

2105 Network Interface Module

Data Handling and Communications

2191 Battery Module

The 2151 Flow Meter is the intrinsically safe version (CSA approved for Class 1, Div 1 environments) of the 2100 series Area Velocity Flow Meter. To ensure proper application, the 2151 uses a distinctive color, and has connectors that are compatible only with other intrinsically safe 2100 Series components. Highly efficient power management provides battery life up to 8 months. 

The area velocity method gives you greater accuracy where weirs and flumes are not practical, and where submerged, full pipe, surcharged, and reverse flow conditions may occur. You don't have to estimate the slope and roughness of the channel, and silt correction allows you to compensate for debris that accumulates on the bottom of the channel. 

Isco Flowlink Software is required to set up the 2151, and to retrieve and analyze stored data. All data is stored in "flash" memory, protecting your data against glitches that can cause other storage technologies to lose your valuable data forever.

Standard Features

• Up to 8 month battery life. 2151 reads out battery voltage to let you know when to change batteries.
• Rugged, submersible enclosure is permanently sealed to meet NEMA 4X, 6P and IP68 requirements 
• Easy to upgrade. New operating software can be downloaded into non-volatile "flash" memory via PC connection, without affecting stored program and data. 
• Measure shallow flows in small pipes. The low profile Area Velocity sensor minimizes flow stream obstruction and senses velocity in flows down to 1 inch (25 mm) in depth. 
• Chemically resistant. The epoxy-encapsulated sensor withstands tough applications.
• Rollover memory with variable rate data storage, lets you change the data storage interval when programmed conditions occur. 
• Pressure transducer venting system automatically compensates for changes in atmospheric pressure to maintain accuracy 
• Quick connect area velocity sensor can be easily removed and interchanged in the field with no recalibration. 
• High-capacity internal desiccant cartridge keeps the vent free of moisture during normal operation 
• Replaceable hydrophobic filter protects against intrusion of water during submersion. 
• Sealed AV sensor resists fouling by oil and grease, eliminating frequent cleanings needed with electromagnetic probes. 
• 38.4k baud communication provides speedy setup and data retrieval.

The 2151P Flow System is similar to the 2151 intrinsically safe Area Velocity Flow Meter, but is designed to operate from AC power for long-term or permanent applications rather than from battery power for shorter-term, portable applications. Like all 2100 Series modules, the 2151P is set up via connection to a computer running Flowlink Software. 

The intrinsically safe design of the 2151P module and flow sensor allows them to be installed in Class I, Division 1, Groups C and D hazardous locations. The concept of intrinsic safety is to limit the energy available to a given circuit or device to a level where electrical discharge (sparking) cannot ignite the hazardous (flammable or explosive) atmosphere. With no spark ignition possible, the equipment can operate safely in areas with hazardous atmospheres. 

A CSA-approved 12V DC (±5%) intrinsically safe power supply is mandatory. Power is fed to the 2151P through an attached cable from the safe area. Remote flow monitoring is possible through the use of Isco’s 2103 Modem Module or 2108 Analog Output Module. 

The standard 2100 Series flow modules are designed so that you can expand or reconfigure a monitoring system by stacking modules. Because of safety requirements, the 2151P is not compatible with the direct stacking of additional 2100 series modules which are not intrinsically safe. 

Other 2100 series modules, including the 2101 Field Wizard and 2103 Modem, can be connected via the Network Barrier Cable or Network Isolator.

Standard Features

• Rugged, submersible enclosure meets NEMA 4X, 6P and IP68 requirements.

• High-capacity internal desiccant cartridge keeps the vent free of moisture during normal operation. 
• Pressure transducer vent system automatically compensates for atmospheric pressure changes to maintain accuracy. 
• Replaceable hydrophobic filter protects against water intrusion during submersion.
