Notes: Compatibility material / medium Please check the compatibility of the given materials with your medium Solid matter laden gases When measuring in solid matter laden gases the sensor VA ought to be cleaned from time to time as necessary. The time interval depends on the type and content of the solid matter. The particles must not be abrasive. Cleaning VA sensors Notes on cleaning the sensors can be found in the manual. Moisture or condensate in gases Moisture in gases is of no disadvantage as long as condensate does not set in. Should condensate arise then it can influence the measurement. The limitations between 100% saturated flow of gas, partial condensate attack on the sensor, severe or slight continuous condensate attack are flowing.The probability of condensate influencing measurement can be kept to a minimum by ensuring that the probe is horizontally positioned in the case of partial or slight condense making drainage at the strut and ultrasonic sender and receiver easier. Input and output sections When measuring in a measurement section of inside diameter Di it must be observed that optimal measurement accuracy when converting the local velocity vp to the average velocity vm = vp ⋅ PF (PF = profile factor) is only guaranteed for when input/ouptut sided irrotational flow prevails and in addition the condition • 20 Di straight, undisturbed input section • 10 Di straight, undisturbed output section is met with. Should a suitably long, straight section line not be available then the measurement cross section is to be placed so that 2/3 of the straight pipe section are in front of the measurement cross section and 1/3 behind the measurement cross section.
