Abstract
A sampling device allows samples to be taken from a fluid that is pressurized and/or contains volatile components. The sampling device has a sampling housing (121, 521), an inlet (10, 110, 510), an outlet (11, 111, 511), a measuring cell (17, 317, 517) and a valve unit (118, 534). The valve unit has a valve which, in a first position, connects the inlet to the outlet by way of the measuring cell. In a second position, the valve connects the inlet directly to the outlet, while also disconnecting the measuring cell from both the inlet and the outlet. The valve unit also has at least one adjustable flow restrictor, through which the flow of the fluid through the sampling device is regulated.
Claims20
A device for taking samples from a fluid that is pressurized and/or contains volatile components, the device comprising:
- a sampling housing;
- an inlet;
- an outlet;
- a measuring cell;
- and
- a valve unit, comprising:
- a valve which, in a first position, connects the inlet to the outlet by way of the measuring cell and which, in a second position, connects the inlet to the outlet directly while simultaneously disconnecting the measuring cell from the inlet and the outlet;
- and
- at least one adjustable flow restrictor arranged to regulate the flow of the fluid through the sampling device.
A device for taking samples from a fluid that is pressurized and/or contains volatile components, the device comprising:
- an inlet;
- an outlet;
- a measuring cell;
- and
- a valve unit for directing flow of the fluid from the inlet to the outlet, the valve unit comprising:
- a valve seat;
- and
- a substantially cylindrical valve body held therein, the valve body arranged for rotation about a longitudinal axis thereof, such that, in a first rotational position, the valve body connects the inlet to the outlet by way of the measuring cell and, in a second rotational position, the valve unit connects the inlet to the outlet directly while simultaneously disconnecting the measuring cell from the inlet and the outlet;
- and
- at least one adjustable flow restrictor arranged to regulate the flow of the fluid from the inlet to the outlet.
