Differential pressure mass flow sensor for gas
TFI4
systec Controls
A mass measurement for gas according to the differential pressure principle typically consists of a primary element (eg orifice, venturi or nozzle), a differential pressure sensor, a pressure sensor, a temperature sensor and a computing unit that calculates the mass flow or standard volume flow. truckflow combines these five components to the smallest and fastest dp-gas mass flow meter.
Meter quality starts at the front - with an optimal tube profile
The primary element is a miniature pitot tube with a patented tube profile, which is in user for thousands of demanding industrial applications (see deltaflow). In cotrast to thermal mass flow meters (HFM) superficial deposits such as oil films and particles have influence on the reading. The flow-optimized-pitot profile ensures a perfect linearity over a huge span. The pressure losses are largely negligible.
