Digital display standard metal measuring apparatus for continuous measurement

Abstract

The invention relates to a digital display standard metal measuring apparatus for continuous measurement, comprising a liquid-receiving funnel, a digital display dial indicator, an ejector rod rack, a gear wheel, a connecting rod, a floating ball, a liquid level glass tube, a slide caliper, a liquid drainage valve, a standard metal measuring apparatus, a horizontal adjustment seat and a measuring apparatus bracket, wherein the liquid-receiving funnel is arranged at the top of the metal measuring apparatus; the metal measuring apparatus is arranged nearby the metal measuring apparatus; the ejector rod rack is connected to the lower part of the digital display dial indicator; the gear wheel is connected with the ejector rod rack and the floating ball through the connecting rod; the liquid level glass tube and the slide caliper are arranged at one side of the standard metal measuring apparatus; the liquid drainage valve is arranged at the lower part of the standard metal measuring apparatus; the measuring apparatus bracket is arranged at the bottom of the standard metal measuring apparatus; and the horizontal adjustment seat is arranged at the bottom of the bracket. Compared with the prior art, the digital display standard metal measuring apparatus for continuous measurement has higher precision, reduces operating errors because of utilizing a full-automatic data collection system, and can replace the manpower reading standard metal measuring apparatus and reduce the labor intensity.

Description

technical field [0001] The invention relates to a weighing appliance, in particular to a digital display type continuous measurement standard metal measuring instrument. Background technique [0002] The standard metal gauge is the standard for volume measurement in the metrology department. Due to the high accuracy of measurement, the reading method has been manual reading so far. Therefore, in order to ensure the accuracy of volume measurement, a glass with a scale has to be installed on the gauge. The tank neck of the window, so that the well-trained measurement personnel can read the liquid level from the glass window, the error will not exceed 0.2mm, and because the diameter of the tank neck is small, the volume reading error caused by the 0.2mm liquid level reading error, the corresponding Because the entire volume is very small, it can be guaranteed to be within the required accuracy range. [0003] However, a 50-liter standard metal gauge can only be used at about 5...

Problems solved by technology

[0003] However, a 50-liter standard metal measuring vessel can only be used at about 50 liters. If a certified container is 51 liters, a 50-liter standard container must be equipped during operation, plus a 1-liter standard container

If an 88-liter container is verified, the measurement personnel must carry 6 standard containers of 50 liters, 20 liters, 10 liters, 5 liters, 2 liters, and 1 liter, and each of them must be operated once for each measurement. It is known that the metrology and verification personnel have troubles when equipped with standard containers and operations, and more importantly, one more operation will cause more errors, which will increase the entire measurement error
