<p>A conductivity sensor comprising a housing 3, 5 defining a flow conduit for the passage of a fluid and electrodes 7.1-7.3 spaced apart along said flow conduit. Excitation circuitry and processing circuitry are operable to connect to said electrodes and operable to determine conductivity measurements of fluid flowing through the housing. At least a part of said excitation and processing circuitry is mounted on a circuit board 11 that is connected to said electrodes by edge connectors 19.1-19.3 that are each directly attached to said circuit board and to an edge of a respective one of the electrodes. The edge connectors may comprise one or more barbs (33, Fig.3B) for gripping the edge of the electrode when inserted into the connector.</p> |
