ABSTRACT:
A sensor assembly for a magnetic flowmeter is provided that is cost-effective to manufacture, while incorporating an effective seal against leakage and enabling precise positioning of electrodes. The sensor assembly includes an electrode assembly and a plastic housing molded about the electrode assembly. The electrode assembly includes an electrode and a plastic base disposed about the lower end of electrode. The housing includes a wall in direct contact with the plastic base such that the tip of the electrode projects from the wall, facilitating a secure seal about the electrode. The sensor assembly further includes a magnetic assembly configured to provide a magnetic field extending beyond the wall of the housing.
