The calculation formula of the measurement process: if the d---- setting value is the density value (unit: Kg/m3)
(1) Vortex flowmeter working volume flow calculation formula:
(2) Density d in Kg/m3
(3) Mass flow calculation formula (if the unit after compensation is U.0), then:
(4) Mass flow calculation formula (if the unit after compensation is U.1), then:
Calculation formula of LUGB-50 vortex flowmeter measurement process: if d----setting value is gas compensation coefficient (dimensionless)
(1) Vortex flowmeter working volume flow calculation formula:
(2) Gas compensation coefficient d (unit 1), which is calculated by the user through operation:
P1 - working condition absolute pressure, PN - standard condition absolute pressure (Mpa), T1 - working condition thermodynamic temperature, TN - standard condition thermodynamic temperature (K)
Gas compression factor, usually defaults to 1
(3) Formula calculation formula (if the compensation unit is U.0):
(4) Formula calculation formula (if the compensation unit is U.1):
Note: The standard condition refers to the parameter setting convention of LUGB-50 vortex flowmeter at 20°C and 1 standard atmospheric pressure (please read the following agreement carefully before setting the parameters):
(1) When setting various parameters, the prompt flash indicates that the parameter has not been set or has not been confirmed. It can be confirmed by pressing the SET button or the button is pressed; the prompt does not flash indicate that the parameter has been set and confirmed At this point, you can press the SET button to page or press the button to exit.
(2) Enter the parameter settings, you need to enter the password and confirm the entry, in order to prevent accidental access to the parameter setting menu, to ensure the normal operation of the instrument, when setting the password, when using the key to adjust the number of cycles can not be repeated, can only single adjustment; After entering each parameter setting menu, you can adjust the data for each bit of each parameter by pressing and holding the key (0-9 cycles).
(3) For the parameter option that can set the decimal point, first set the decimal point and confirm, then set and confirm the parameter data.
LUGB-50 vortex flowmeter
LUGB-50 vortex flowmeter is mainly used for flow measurement of medium fluid in industrial pipelines, such as gas, liquid, steam and other media. Its characteristics are low pressure loss, large range, high precision, and almost no influence of parameters such as fluid density, pressure, temperature, and viscosity when measuring volume flow. No moving mechanical parts, so high reliability and low maintenance.
