The FB39 flow measuring devices have been released by Alvi Technologies for determining the flow of highly reactive gases and liquids by differential pressure.
The compact FB39 flow sensor encompasses a plastic-holed plate and a flange-linked flow transmitter without having any mobile parts. The wet plastic sections of the device are constructed from PVDF or PP based on the nature of the media.
The potential of the device to resist even hazardous media has made it suitable for wastewater treatment, water treatment and electroplating purposes. The device offers a flow proportional output signal ranging from 4 to 20 mA and also features additional display and switching contact.
The flow metering part has an opening with tapping holes for differential pressure and combines two pressure sensing units and electronics in a single enclosure. The differential pressure generated at the opening is calculated using the two pressure sensors and is transformed into a high-quality electronic signal.
The components in the calculated medium are made of chemical-proof plastics and the pressure sensing units are fabricated out of standard ceramic (99.6% AL2O3 ceramic). The device has a calibrating range of about 40m³/h and is IP65-certified.
