FIELD: physics; measurement. ^ SUBSTANCE: proposed device for controlling temperature of a flow measuring device with a measuring pipe, designed for measuring weight flow, density and/or viscosity of a process medium, contains at least one heat exchanger, detachably fitted outside the measuring device. The inner wall of the heat exchanger is in contact with the outside of the measuring device at least by part of the surface and is channel-shaped or has a cupped-convex shape. The outer wall is fixed on the inner wall, joined to the inner wall along the peripheral section by a joining seam, airtight for the temperature control medium, and several point or ring-shaped inner junction points, at a distance from each other on the inner section enclosed by the peripheral joining seam. Between the inner and outer walls of the heat exchanger, there is a cavity (H) for inlet of the temperature control medium, containing several interconnected sections. Cavity (H) is connected to the pipe system for supplying the temperature control medium through an opening on at least one of the walls of the heat exchanger. The temperature controlling device can be manufactured easily. ^ EFFECT: provision for high thermal efficiency at relatively high hermeticity and thermal stability. ^ 31 cl, 19 dwg |
