Introduction

This procedure is prepared in accordance with JJF1002-2010 "Rules for the preparation of national metrological verification procedures", and Compared with JJG 1045-2008, in addition to editorial changes, the main technical changes are as follows. --- Added introduction; --- Added reference files (see 2); --- The choice of "special weight" has been added to the terms and units of measurement (see 3.2); --- "Discrimination [threshold]" changed to "discrimination" (see 3.3); --- The unit of measurement is changed from kg/m3 as the main unit to g/cm3 as the main unit (see 3.4); ---Measurement of measuring instruments including initial inspection, subsequent verification and use of "inspection" into "inspection" (see 7); --- Added additional equipment such as level, pure water, absorbent cotton, tweezers, hair dryer (see Table 2); --- The ambient temperature in the environmental conditions is changed from (5~40) °C to (20±5) °C, and the ambient humidity is not greater than 85% is changed to no more than 75% (see 7.1.2); --- Zero adjustment adds a zeroing method for mud density meters that do not contain 1.000g/cm3 in the measurement range (see 7.2.1.3); --- In the processing of the verification results - indicate that the "cause" of the failure is changed to "project" (see 7.3); ---Atmospheric pressure (0-40) °C air-free pure water density meter changed from t68 to.1990 international temperature scale t90 (see Appendix D). The previous versions of this procedure are released. ---JJG 1045-2008. Mud density meter verification procedure

1 Scope

This procedure applies to the first verification, subsequent verification and in-use inspection of mechanical and electronic mud density meters. its His similarity to the density meter can be calibrated with reference to this procedure.

2 reference files

This procedure refers to the following documents. JJF1229-2009 Terms and definitions of mass density measurement For dated references, only the dated version applies to this Code; any undated quotation The latest version (including all amendments) applies to this procedure.

3 terms and units of measure

3.1 replacement refil Granular materials with a bulk density of more than 5.5 g/cm3, such as copper, stainless steel, lead, etc. (4-10). 3.2 special weight specialweight A metal object having a diameter of less than 5 cm and a shape symmetry or a solid substance having a density close to that of a metal. 3.3 discriminating force discrimination The mass of the largest weight that causes the mechanical mud densitometer to produce an undetected response change.

4 Overview

A mud density meter is an instrument used to measure mud density. The volume of the sample cup is known, and the mud is measured by the weighing method. The mass of the slurry is measured to determine the density of the slurry. Mud density meters are divided into mechanical and electronic types. Mechanical mud The gauge is mainly composed of a support and a lever with a scale. Place the sample cup at one end of the lever and the crucible at the other end. Fill the sample cup with the sample to be tested, move the crucible to balance the lever, and the scale corresponding to the crucible indicates the sample to be tested. density. Mechanical mud density meter is divided into normal pressure mechanical mud density meter according to the internal pressure of the sample cup. (See Figure 1) and a pressurized mechanical mud density meter (see Figure 2). Electronic mud density meter through force sensor measurement The quality of the product, the digital display converts the mass electrical signal into a sample density and displays. Electronic mud density meter from sample The cup, force sensor and digital display (see Figure 3). The mud density meter is suitable for the measurement of mud density in road and bridge construction and the density measurement of drilling fluid. Pressurize Mechanical mud densitometers are used to measure samples containing air or natural gas. ......
