![]() This ensures the accuracy of the measurements. The measuring tubes to the dP sensor are equipped with automatic compressed air purges that are periodically activated to avoid pollution in the measuring tubes. The measurement equipment can be used for processes using both Air as Gas. We have two standardized units ready to be assembled. The flow measurement unit can be adapted and customized to your specific needs. Flow Measurement Equipment features and options This is all depending on industry, product and process. This way, inspection hatches are not needed as well.įlow Measurement Devices can go by many names like: Flow meters, flow instrumentation, flow indicator, flow rate sensor or flow gauge. The measurement units have quick connections on both sides of the device to achieve easy inspections or replacements without intervening largely with your production process. Installing multiple units per production line, also gives more information about process performance. ![]() How to measure the velocity or volume of Air and GasĮasily put, Flow Measurement Units or ‘Flow Meters’ measure air or gas flows and volumes before and after an intervention. Through the years, we have designed a better performing unique shape compared to an orifice plate. Normal pitot, measuring tubes, hot-wire or orifice measurements can often pollute relatively quickly, resulting in unreliable measurements.Īs our devices are designed for differential pressure measurement over a restriction, the pollution over a restriction causes much less pollution. With JOA’s Air Flow Measurement Devices, you will be able to prevent pipe pollution and recognize additional improvements to your process. The downtime from maintenance can lead to many unwanted delays, let alone the impact it has on your operators and maintenance department. Polluted pipes in your process can be a real threat to productivity and explosion safety (ATEX). Measuring the CO2 level thus makes it possible to determine the necessary ACR of a room depending on the number of occupants and the nature of their activity within a room. For instance, a gym requires a higher ACR than an office room for the same occupancy, as athletes exhale more CO2 (and also biological contaminants) per minute.Why should you continuously gather data from your production process? The CO2 level is the preferred indicator of the air change rate in a room because it is relatively easy and reliable to measure using a CO2 Meter or a professional CO2 sensor, and above all because it takes into account the exhalation of the people occupying a room. This rate is often expressed as the number of complete cycles of renewal of the entire volume of air in a room in one hour (that’s why it is also called ACH as for Air Change rate per Hour). Insufficient air renewal will increase the concentration of these harmful and even dangerous components, especially when many people occupy the affected area.Ī balometer can easily measure the amount of air entering a room in a given time, and relate this to the total volume of the room to derive an air change rate. The rate of air renewal inside a room is a very important parameter to know if the indoor air is sufficiently stirred to reduce the concentrations of harmful gases such as CO2 and VOCs, polluting particles, not to mention biological compounds such as viruses and bacteria. Key role in controlling the air change rate (ACR) Utilizing application proven thermal mass flow technology, the FS10i provides a highly accurate and repeatable linearized 4-20 mA output of flow rate. It is the first, and currently only, thermal mass flow meter to meet SIL 2. Note that as modern balometers are primarily pressure measuring instruments, they can also be used as micro-manometers by connecting Pitot tubes or simple silicone tubes to them. The FS10i is a compact, economical solution to air and compressed air flow metering. ![]() Sufficient airflow facilitates the maintenance of the temperature and humidity levels targeted by the professionals in charge of managing the building's ventilation system. The balometer is precisely the only instrument capable of providing a reliable and accurate measurement on a certain type of air vent: diffusers, whose omnidirectional airflow is very difficult to measure with a conventional anemometer. This system allows to calculate very precisely the airflow that passes through a vent, and therefore the total airflow that enters or leaves a room. A balometer is accompanied by different measuring hosts to be applied according to the size and shape of the air vents in a room, both supply and exhaust.
