Title:
ELECTRONIC WEIGHING DEVICE HAVING FLOW CALCULATION FUNCTION
Document Type and Number:
WIPO Patent Application WO/2014/112398
Kind Code:
A1
Abstract:
Provided is an electronic weighing device, such as an electronic balance, having a flow calculation function, which is able to eliminate an error that occurs when the flow is calculated and accurately obtain an exact flow measurement result. An electronic weighing device having a flow calculation function comprises: a load sensor unit (1) which is provided with a weighing table (1a); a clock generation circuit (4) which generates a reference time signal; an A/D conversion unit (2) which converts an analog load signal outputted from the load sensor unit (1) into digital load data every time receiving the reference time signal; an arithmetic processing unit (3) which converts the load data outputted from the A/D conversion unit (2) into a weighed value by performing a correction operation every time receiving the reference time signal, calculates the change amount per unit time of the weighed value, and finds the flow amount; a display unit (6) which displays data such as the weighed value or a flow amount value outputted from the arithmetic processing unit (3); a memory (5) which stores various kinds of data; and an input/output unit which is composed of a key switch unit (7) and an interface unit (8) and to/from which the various kinds of data are inputted/outputted.
