Pressure Sensor Status
The pressure at the BladeMeter is measured with a pressure sensor. A second sensor may be used to measure the pressure in the main pipeline immediately before the junction to the spur that leads to the BladeMeter. Changes in BladeMeter and trunk pressure are monitored to detect trends that might indicate changing conditions within the pipeline.
