In the method for calibrating a flow meter, at least two acoustic sensors are arranged at a distance to each other on a straight measuring portion, and a tracer is fed into the fluid flowing in the process pipe at a set mixing distance from the first measuring point. The momentary ...
Method of testing and calibrating a mass flow meter e.g. in flow-line of IC-engineThe method involves connecting a mass flow meter to be tested flow-wise in series with a reference mass flow meter, and varying the gas flow in the flow channel through both mass flow meters with regard ...
Method and apparatus for calibrating flow meterdoi:CN101014839 AA method and apparatus is disclosed that determines the time delay (202) between the actual flow and the measured flow in a flow meter. The time delay is used to shift the flow measured by the flow meter to correspond to the ...
1.To check, adjust, or determine by comparison with a standard (the graduations of a quantitative measuring instrument):calibrate a thermometer. 2. a.To make corrections in; adjust:calibrated the polling procedures to ensure objectivity.
PURPOSE:To calibrate a flow rate having any size at the same place by providing plural provers which differ in reference capacity, and switching a valve to a flow meter to be calibrated and connecting a prover having proper capacity. CONSTITUTION:Piston type provers 10 and 20 which differ in ...
METHOD FOR CALIBRATING FLOW METERS FOR FLUID MEDIA A method for calibrating flow meters for fluid media comprises the steps of guiding a medium (102) through a reference measuring section (101-1) and a test measuring section (101-2) which has a flow meter to be calibrated, establishing a....
PURPOSE:To attain safe flow meter calibrating operation without interrupting the operation of the process by closing the inlet and outlet of a branch passage during the calibrating operation whereas by closing the inlet and outlet of the piping for calibration in the normal operation of the process...
A method of calibrating wavemeters in the microwave range is described in which the frequency of a calibrating oscillator having sufficient power to drive ... LE Hunt - 《Proceedings of the Ire》 被引量: 1发表: 1947年 Application Study on Hot Wire Type Air Flow Meter Used in Portable Exhau...
The uncertainty of measurement of CO2under test conditions is hardly affected by temperature, pressure and flow rate conditions within the range investigated in this study. 展开 关键词: CCS CO2 metering Carbon dioxide Coriolis meter Uncertainty ...
