Abstract
An instrument for measuring density, with a housing (1) and a measurement cell (2) arranged therein. The housing has an inlet opening and an outlet opening for a fluid sample, with a first adapter (12) for connecting the inlet opening to a sample reservoir (14), with a second adapter (11), for connecting the outlet opening to a waste container (15), and with an adapter housing (13), which is attached to the housing. The adapter housing comprises a feed-through for the first and second adapters, characterized in that the adapter housing is designed in one piece, and the adapters can each be affixed in the adapter housing first fastening means without tools.
Claims13
An instrument for measuring density of a fluid sample, comprising:
- a measurement cell;
- a housing in which the measurement cell is arranged, the housing comprising an inlet opening and an outlet opening for the fluid sample;
- a first adapter, tapered at a first end for insertion into the inlet opening and adapted at a second end for connection to a reservoir containing the fluid sample;
- a second adapter, tapered at a first end for insertion into the outlet opening and adapted at a second end for connection to a waste container for the fluid sample;
- and
- an adapter housing, which is designed in one piece for attachment to the housing, the adapter housing having a receptacle area that comprises a first and a second receptacle providing a feed-through for each of the first and the second adapters, a split of the receptacle area through the receptacles allowing transverse compression of an intermediate portion of each adapter in its receptacle.
An instrument for measuring density of a fluid sample, comprising:
- a measurement cell;
- a housing in which the measurement cell is arranged, the housing comprising an inlet opening and an outlet opening for the fluid sample;
- a first adapter, connecting the inlet opening to a reservoir containing the sample;
- a second adapter, connecting the outlet opening to a waste container for the fluid sample, the first and second adapters comprising a material that is at least semitransparent, so that impurities of the fluid sample are visually discernible therethrough;
- an adapter housing, designed in one piece of a mixture of polyether ketone and carbon, the adapter housing attached to the housing and comprising a feed-through for each of the first and the second adapters;
- and
- means for compressively affixing the respective adapters in the adapter housing.
