FIELD: physics.
SUBSTANCE: measurement pipe (1) of the measurement sensor of a magneto-inductive flow metre built into a pipeline consists of a support metal pipe (2) having a lining (3) inside. There is a layer of binding liner (4) for joining the lining and the support pipe. The lining and priming coat are made from polyurethane suitable for drinking water. The priming coat is obtained by depositing and hardening a first multi-component system containing isocyanate, particularly diisocyanate, as well as two, or a polyatomic alcohol, and the lining is obtained by depositing a second multi-component system onto the priming coat and then holding, where the second multi-component system contains isocyanate, particularly diisocyanate, two, or a polyatomic alcohol and a catalyst.
EFFECT: measurement device meets high chemical-biological and hygiene requirements for use in drinking water, device is cheap to make.
