Isco 2151 Intrinsically Safe Area Velocity Flow System

Isco Product Data Isco 2151 Intrinsically Safe Area Velocity Flow System The 2151 AV Flow System is the intrinsically safe version (CSA approved for Class I, Div. 1, Groups C & D environments) of Isco’s 2150 Area Velocity Flow Meter.

To ensure proper application, 2151 has unique connectors that are compatible only with other intrinsically safe 2100 Series components. 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.

The flow rate is then calculated by multiplying the area of the flow stream by its average velocity. 2151 is powered by two alkaline batteries. Highly efficient power management provides a battery life of up to 8 months in a typical setup. Applications Open channel flow measurement in hazardous locations (ATEX Category 1G).
