As an insertion meter
, flow in large pipes can be measured and the Hot Tap model can be used to measure pipes from 2 to 24-inch (50 to 1200mm).
ABB Limited has enhanced its AquaProbe insertion meter
range with a three year warranty period as standard, with an added two year purchase option if required.
Nice Instrumentation introduced its first insertion meter
, called the Vortex Bar, three years ago.
The insertion meter
may be installed or removed from an active line without interrupting service.
Low flow measurements were taken with a Daniel's Senior orifice fitting and the high flow measurements were taken using a Preso insertion meter
Insertion meters are widely used for flare and duct stack gas measurement.
While they may be less accurate than inline meters, insertion meters are typically less expensive than inline meters.
Ultrasonic flow meters come in the form of either clamp-on, spoolpiece or insertion meters
can be installed under pressure using special hot-tap techniques and pipe clamps avoiding the need to switch off compressors and stop production.
Thermal sensors come in three basic forms: hot wire anemometers or insertion meters
, thermal profile or bypass meters, and clamp-on thermal meters.
The calibration manifold can accommodate wafer meters from 1/2-inch to 4 inches in diameter, along with insertion meters
in a 6-inch diameter pipe.
are and to measure flare gas in stacks, and ultrasonic flowmeters are used more widely in the chemical and refining industries.
