Abstract

There is shown and described a mass flow measuring system for measuring the flow rate of a fluid in a sensing tube over a wide ambient temperature range and with low sensitivity to attitude change. The improvement is directed to the insulating material which is used with the system and the means for producing an isothermal plane around the system.
