Description
The Aalborg 503940 Mass Flowmeter is a device designed to measure the rate of fluid flow with a high degree of accuracy. It excels at measuring low flow rates, ranging from 0 to 5 liters per minute. This makes it suitable for applications in various fields such as research laboratories, medical facilities, and industrial settings where precise control of small amounts of fluids is critical. Unlike traditional flow meters that measure volume, mass flowmeters like the 503940 are less affected by pressure fluctuations, leading to more reliable readings.
Specifications:
- Flow Range: 0 – 5 L/min
- Accuracy: ±(0.8% of Reading + 0.2% of Full Scale)
- Repeatability: ±(0.2% of Reading + 0.1% of Full Scale)
- Maximum Operating Pressure: 150 PSIG (10.3 bar)
- Maximum Operating Temperature: 50°C (122°F)
- Analog Output Signal: 0-5 VDC, 4-20 mA, or 0-10 VDC (selectable)
- Power Supply: 12-28 VDC
