Inline Gas Flow Sensor -- ESRF-ESF

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 ±300 ln/min with a total error band of < 1.25% RD. ESRF-ESF gas flow sensors provide calibrated and temperature compensated output on an SPI, I2C bus or analog output making them plug & play for direct interfacing to low voltage MCUs and systems. The user is provided with a multitude of interface and output options so that the right sensor configuration can be selected based on the specific requirements for each application. Due to the compact design, and versatility, ESRF-ESF gas flow sensors are ideal for medical, process & pharmaceutical equipment where high accuracy and reliability are of the essence. Calibration gas is air but other non-aggressive gases are available upon request.
