2. Structure and operating principle
SBL flowmeter mainly consists of measurement tube (casing), stress element (target plate), sensing elements (force transducer, pressure transducer and temperature transducer), transition part (adjusted according to temperature and pressure), and accumulation calculation, display and output part. Refer to the following figure for the structure:
When flow medium flows through measure tube, a pressure will force on the target because of the flow kinetic energy. It is known that the pressure value forcing on the target can be expressed as
F — Pressure on the target
CD — Damp index
A — Area of target on axial projection to measure tube
P — Medium density
U — Mean velocity of medium
