Embodiment Construction

[0022] The measuring device according to the invention, in the present case a measuring device for determining the density of liquids, comprises a bending oscillator 12 which is arranged inside an advantageously open housing 20 and which is connected to the The housing 20 forms the measuring chamber 1 . The liquid to be tested (as is known per se) is fed or conducted at its end to the bending oscillator 12 and the measured values ​​of the oscillations are received and evaluated. The units required for this are known and not shown. as in figure 1As schematically shown in , the measuring device 4 includes a measuring chamber 1 which accommodates a bending oscillator 12 in its housing 20 and includes a corresponding sample supply 22 . Measuring device 4 also includes condition monitoring unit 2 with memory unit 21 , which contains stored prediction and forecast algorithms for expected changes in ambient parameters during the course of the measurement. An adjusting element 3 is...

Abstract

The invention relates to method for determining the density of liquids, and particularly relates to a method and measuring device for determining the density of liquids. The measuring device has a flexural resonator, at least one sensor for at least one environmental parameter that influences a measurement to be performed and a condition monitoring unit. The measured values from the respective sensor are fed to the condition monitoring unit. The condition monitoring unit has a memory unit with stored forecasts for environmental parameters to be expected in the course of the measurement, and that, by using the condition monitoring unit, on the basis of the stored forecasts and the initial measured values selected for the measurement, it is determined whether the planned measurement can be carried out under the selected trial conditions without any impairment or with a permissible impairment by the forecast changes in the environmental parameters.

Description

technical field [0001] The invention relates to a method according to the preamble of patent claim 1 and a measuring instrument for carrying out the method according to the preamble of patent claim 6 . Furthermore, the invention relates to a data carrier on which is stored a computer program for carrying out the method according to the invention. Background technique [0002] To accurately determine the density of a fluid with a bending oscillator, stable ambient conditions and defined operating states of the bending oscillator are required. Otherwise, the measurement can be adversely affected by interfering environmental influences, such as, for example, air pressure, air humidity, temperature, dust particles, chemical vapors, shocks and / or vibrations, up to the permanent presence of interfering influences until the bending oscillator is damaged or damaged. [0003] Especially for a highly accurate determination of the density of liquids, a stable temperature of the measu...
