From Flow Measurement
Most flow measurements are made by meters that are installed in-line such that
all of the fluid passes through the meter body. Insertion (sampling) flow measurement
is a different technique because the meter is inserted into the pipe and the
flow rate is inferred from the measurement at a point in the flow stream.
There are both similarities and differences between in-line and insertion techniques.
On the one hand, fluid properties, pipe flow phenomena, and the basic
principles of flow sensing are the same. There are significant differences, however,
in operating principles, installation, and applications.
|What Is an Insertion Flowmeter?|
An insertion flowmeter consists of three basic components: a sensor, a probe
assembly, and electronic circuitry. The sensor provides a signal proportional to the
velocity or flow rate at a point in the flowstream from which total flow rate is
inferred. The circuitry properly conditions the raw signal from the sensor and performs
required computational functions. The probe assembly rigidly positions the
sensor within the flow and provides a process seal.
