The utility model has the beneficial effects that: according to the utility model, the three pipelines are clamped and fixed through the front clamping plate, the rear clamping plate and the connecting piece, so that on one hand, the fixed spacing among the three pipelines is ensured to be constant, the pressure pipe is heated more uniformly, and on the other hand, the three pipelines can be fixed more stably. In order to further improve the installation stability of front splint, back splint for front splint, back splint can be inseparabler with the contact between the three pipeline, prevent not hard up, all be provided with on front splint and the back splint respectively with the three U-shaped buckle of negative pressure pipe, positive pressure pipe and the mutual adaptation of industry steam heat tracing pipe outer wall. In order to improve the installation and maintenance efficiency, the connecting piece is a screw and nut assembly which can mutually tighten and fix the front clamping plate and the rear clamping plate. The utility model effectively solves the problems that the pressure guide pipe of the instrument is heated unevenly, the positive pressure and the negative pressure generate deviation and the like, and the device has the characteristics of stability and convenient operation and maintenance for measuring and analyzing the media such as gas, liquid, steam and the like. The steam insulation pipeline and the pressure guide pipe are reliably fixed from solving the actual problems on site, so that the pressure guide pipe is uniformly heated, the failure rate and the maintenance time are reduced, and the steam insulation pipeline and the pressure guide pipe can be widely applied to industry. The utility model has wide application occasions and effectively solves the problem of soaking of the steam heat-preservation pipeline in the cold region. The differential pressure type flowmeter measuring device is reasonable in structure and convenient to install, achieves the purpose of improving the accuracy and stability of measurement of the differential pressure type flowmeter, meets the requirement of instrument installation, provides convenience for later maintenance and repair, and can enable the instrument to achieve the accurate measurement effect.
