Maximum Allowable Level 34 ft (10.5 m) Accuracy ±0.01 ft from 0.033 to 10 ft, (±0.003 m from 0.01 to 3.05 m,) Long-Term Stability ±0.023 ft/yr (±0.007 m/yr) Compensated Range 32° to 122°F (0° to 50°C) Velocity Measurement: Method - Doppler ultrasonic, frequency 500 kHz Typical Minimum Depth 0.08 ft (25 mm) Range -5 to +20 ft/s (-1.5 to +6.1 m/s) Accuracy (in water with uniform velocity profile, speed of sound = 4850 ft/s, for indicated velocity range) ±0.1 ft/s from -5 to 5 ft/s (±0.03 m/s from -1.5 to +1.5 m/s) ±2% of reading from 5 to 20 ft/s (1.5 to 6.1 m/s) Temperature Measurement: Accuracy ±3.6° F (±2° C) Isco 2150 Area Velocity Flow 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. Standard Features 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. ♦ Replaceable high-capacity internal desiccant cartridge and hydrophobic filter protect sensor reference from water entry and internal moisture. Size (HxWxD): Weight (without batteries): High-impact polystyrene, stainless steel Enclosure (self certified): Two 6-volt Energizer Model 529* alkaline (25 Ahrs capacity) or Isco Rechargeable Lead-acid (5 Ahrs capacity) recommended. *Note – Energizer 529 ER does not give specified life. ♦ Portable and permanent-site AV flow monitoring for inflow and infiltration, capacity assessment, sewer overflow, and other sewer studies. 2150 Ordering Information Contact your Teledyne Isco representative for complete ordering details and information on other 2100 Series Modules. 2150 with AV sensor, 2191 Battery Module, and Handle 2150 Module with AV sensor (only) Isco Flowlink® 5 Software Energizer® Model 529 Alkaline Lantern Battery (2 required) Isco Rechargeable Lead-acid Battery (2 required) Charger for Lead-acid Batteries (holds 2 batteries) ♦ Measuring shallow flows in small pipes. Our low-profile area velocity sensor minimizes flow stream obstruction and senses velocity in flows down to 1 inch (25 mm) in depth. ♦ Rugged, submersible enclosure meets NEMA 4X, 6P (IP68) environmental specs. ♦ Chemically resistant epoxy-encapsulated sensor withstands abuse, resists oil and grease fouling, and eliminates the need for frequent cleaning. ♦ Pressure transducer vent system automatically compensates for atmospheric pressure changes to maintain accuracy. ♦ The quick-connect sensor can be easily removed and interchanged in the field without requiring recalibration. ♦ Up to four 2100 Series flow modules can be networked by stacking and/or extension cables. 4700 Superior Street Lincoln NE 68504 USA Tel: (402) 464-0231 USA and Canada: (800) 228-4373 Fax: (402) 465-3022 E-Mail: iscoinfo@teledyne.com Internet: www.teledyneisco.com Teledyne Isco reserves the right to change specifications without notice. © 2012 Teledyne Isco • L-2115 • rev 11/12 Above left: Additional modules can be added for redundant or multi-stream measuring (Isco 2110 Ultrasonic Module shown).
