ARE THE FLOWMETERS BI-DIRECTIONAL?
The flowmeters cannot detect the direction of the flow only the magnitude of the flow. Also the meters are calibrated in the direction indicated by the arrow on the bottom of the flowmeter. See the application note Reverse Flow Effects on TSI General Purpose Flowmeters for the correction for reverse flows.
ARE THERE ANY SPECIAL CONNECTION REQUIREMENTS FOR THE ANALOG OUTPUT?
Yes. The analog signal ground return is connected to the power ground inside the flowmeter. For this reason your equipment must use a voltmeter or analog input circuit with a differential input or floating ground. Failure to use this type of ground will result in measurement errors.
ARE THERE CORRECTION FACTORS FOR THESE DIFFERENT GASSES?
No. These flowmeters are separately calibrated for air and 100% O2. Calibrations for the other gasses involves an internal algorithm in the meter. The desired gas is selected by an RS232 command. Once set, the LCD display indicates the gas calibration. The flow rate displayed on the LCD and the flowmeter?s outputs is then automatically corrected for the selected gas.
ARE THESE FLOWMETERS PRESSURE COMPENSATED?
Yes. The output readings are compensated for pressure changes as long as those pressures changes are within 0.5 to 2.0 atmospheres absolute pressure.
ARE THESE FLOWMETERS TEMPERATURE COMPENSATED?
Yes. The output readings are compensated for temperatures changes as long as those temperature changes are within the temperature-compensated range.
