Isco 2151P Intrinsically Safe Area Velocity Flow System - 1

Isco Product Data Isco 2151P Intrinsically Safe Area Velocity Flow System The 2151P Flow System is the intrinsically safe version (CSA approved for Class I, Div. 1, Groups C& D environments) of Isco’s 2150 Series Area Velocity Flow Meter. Principles of operation Our Area Velocity flow modules use continuous-wave Doppler technology to measure mean velocity. The sensor transmits an ultrasonic pulse, then measures the frequency shift of pulses reflected by air bubbles and particles in the flow. A differential pressure transducer in the sensor measures liquid depth to determine flow area. Flow rate is then calculated by multiplying the area of the flow stream by its average velocity. To ensure proper application, the 2151P uses unique connectors that are compatible only with other intrinsically safe 2100 Series components. A CSA-approved 12V DC 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. Applications Open channel flow measurement in Hazardous Locations (Class I, Div. 1, Groups C & D). Level measurement in potentially explosive areas, such as manholes, digesters and storage tanks. Permanent AV flow monitoring. Dual-module version available Standard Features Rugged, submersible enclosure meets NEMA 4X, 6P and IP68 requirements. Sealed AV sensor resists fouling by oil and grease — no need for frequent cleanings. Chemically resistant epoxy shell withstands harsh elements. Pressure transducer vent system automatically adjusts for atmospheric pressure changes to maintain accuracy. Quick-connect area velocity sensor can be easily removed and interchanged in the field without needing recalibration. High-capacity internal desiccant cartridge keeps vent free of moisture during normal operation. Replaceable hydrophobic filter protects against water intrusion during submersion. An RS 232 Communicator Cable, with built-in barrier, provides safe, in-the-field connection to a laptop computer.

Software Features ➤ Secure data storage. All data are continuously stored in “flash” memory to protect against loss in case of power failure. ➤ Easy to upgrade. New operating software can be downloaded into non-volatile "flash" memory, without affecting stored program and data. Options and Accessories Network Barrier Cable Connects with other 2100 Series modules (such as; modem, wireless, analog output, and Field Wizard) that are located outside the hazardous area. Network Isolator ➤ Records and stores input voltage data for future reference. As above, but designed for DIN rail mounting. ➤...
