HT5 series metal tube flowmeter
7 Caliber
Understanding of traffic:
Valve opening, pump head, Flow rate and pressure size, etc. are no absolute
correspondence, can not represent the size of the flow.
7.1 Determine the correction coefficient Kx
a. A user is given if the liquid volume Flow rate Qv, is calculated by the formula Ka:
b. If the user is given a liquid mass flow rate Qm, is calculated using the formula Kb:
c. If the user is given under standard conditions (0 ℃, 0.1013MPa) gas volume flow Qv ,,
is calculated using the formula Kc:
d. If the user is given the operational state of gas volume Flow rate Qv, is calculated
using the formula Kd:
