Abstract
A viscometer includes a viscosity sensor with a liquid flow channel for measuring a viscosity of a liquid flowing through the liquid flow channel, a manifold with an inlet and an outlet for receiving a liquid sample through the inlet of the manifold and providing the received liquid sample through the outlet of the manifold to the viscosity sensor, and a pump coupled with the manifold for causing an in-flow of the liquid sample into the manifold through the inlet of the manifold and an out-flow of the received liquid sample from the manifold through the outlet of the manifold. Also disclosed is a viscosity sensor module with two or more viscosity sensors.

A viscometer, comprising:
- a viscosity sensor with a liquid flow channel for measuring a viscosity of a liquid flowing through the liquid flow channel;
- a manifold with an inlet and an outlet for receiving a liquid sample through the inlet of the manifold and providing the received liquid sample through the outlet of the manifold to the viscosity sensor;
- and
- a pump coupled with the manifold for causing an in-flow of the liquid sample into the manifold through the inlet of the manifold and an out-flow of the received liquid sample from the manifold through the outlet of the manifold, wherein:
- the manifold includes a first valve coupled with the inlet of the manifold and a second valve coupled with the outlet of the manifold;
- and
- the first valve is mechanically coupled with the second valve so that closing the first valve opens the second valve and opening the first valve closes the second valve.
