US 12,298,206 B2 · Method for filling and/or cleaning the measurement cell of a measuring instrument and measuring instrument

Abstract

A method for fills and/or cleans the measurement cell of a measuring instrument, namely a viscometer and/or density measuring instrument, in particular of a rotational viscometer. A sample is introduced via a sample line into the measurement cell by a pump, and wherein a dynamic viscosity and/or density of the sample is determined in the measurement cell. A funnel-shaped, reversibly openable receiving container, in particular a filling funnel, for the sample, is arranged in the sample line, between the pump and the measurement cell. The receiving container is opened and the sample is introduced into the receiving container. The receiving container is connected to the pump via a pressure line in such a way that, when pressure is applied into the receiving container, a proportion of the sample is dispensed out of the receiving container and introduced into the measurement cell.

Dependent claims

A method for filling and/or cleaning a measurement cell of a measuring instrument, which comprises the steps of:

introducing a sample via a sample line into the measurement cell by a pump;
disposing the sample line and a funnel-shaped, reversibly openable receiving container for the sample between the pump and the measurement cell;
and
opening the funnel-shaped, reversibly openable receiving container so that the sample is introduced into the funnel-shaped, reversibly openable receiving container, wherein the funnel-shaped, reversibly openable receiving container is connected to the pump via a pressure line such that, when pressure is applied into the funnel-shaped, reversibly openable receiving container, a portion of the sample is dispensed out of the funnel-shaped, reversibly openable receiving container and is introduced into the measurement cell.

1 more element

A measuring instrument for measuring a dynamic viscosity and/or a density of a sample, the measuring instrument comprising:

at least one measurement cell;
a sample line;
a pump connected to said measurement cell via said sample line;
and
a funnel-shaped, reversibly closable receiving container for receiving the sample, said funnel-shaped, reversibly closable receiving container and said sample line disposed between said pump and said at least one measurement cell, wherein the sample can be introduced into said funnel-shaped, reversibly closable receiving container, wherein said funnel-shaped, reversibly closable receiving container is connected to said pump such that, when pressure is applied into said funnel-shaped, reversibly closable receiving container by said pump, a portion of the sample is dispensed out of said funnel-shaped, reversibly closable receiving container and introduced via said sample line into said at least one measurement cell.
