Flow Measurement & Control
Developed from aerospace technology, the Verabar velocity averaging pilot flow sensor accurately and reliably measures the flow of gas, liquids or steam. Available from Protea Automation Solutions, the Verabar is a one-piece aerodynamically profiled sensor that is inserted into the flow stream. The sensor shape reduces drag and flow-induced vibration and the location of the low-pressure ports eliminates the risk of clogging and improves signal stability.
The system can be installed in less than one hour. The design ensures that the sensor remains seated, locked and pre-loaded to the opposite wall regardless of changes in pipe diameter due to pressure, temperature or mechanical force. The spring lock design continually compensates for the differential in packing and body growth due to increased temperature.
Verabar is suitable for a wide range of applications for gas (natural, compressed air, hydrocarbons), etc, liquids (boiler feed water, hydrocarbon liquids, cryogenic, etc) and steam (saturated, distribution, super-heated, etc). The manufacturer says that the device is able to pay for itself in less than a year.
