ES Systems has developed ESRF-ESF, an inline gas flow sensor, based on the hot-film anemometer principle for mass gas flow measurements.
ESRF-ESF is one of the few gas flow sensors featuring bidirectional gas flow sensing of up to ±500 ln/min with a total error band of < 1% RD. The streamlined symmetrical body design, manufactured from high-quality plastic, presents a very low-pressure drop even at the maximum flow in both directions. Calibration gas is air, but other non-aggressive gases are available upon request.
Operating down to 5V supply voltage, ESRF-ESF gas flow sensors provide calibrated and temperature compensated output on an SPI or I2C bus making them plug & play for direct interfacing to low voltage MCUs and systems. The user is provided with a multitude of options (e.g. power supply, uni/bi-directionality or analog output) so that the right sensor configuration can be selected based on the specific requirements for each application.
– Bidirectional flow meter (inhale-exhale)
– High accuracy
– Long-term stability
– Flow & temperature sensor combo
– Competitive cost
– Certified (CE) – included in price
