一、概述 CPC型差动膜片差压计(以下简称差压计)是固定安装的工业仪表,配合节流装置可以用来测量各种液体、气体和蒸汽的流量。差压计也可以用来测量压力、吸力及开口或受压容器内的液体的液位。差压计仅适用于测量无侵蚀性的介质,如必需测量侵蚀性的介质时,应加装适当的隔离装置。差压计必须与显示仪表成套使用。根据输出信号的不同,差压计分为A、B二种类型。A型差压计与毫伙计(由上海自动化仪表
First, an overview CPC-type differential diaphragm differential pressure gauge (hereinafter referred to as differential pressure gauge) is a fixed installation of industrial instrumentation, with the throttle device can be used to measure a variety of liquids, gases and steam flow. Differential pressure gauges can also be used to measure pressure, suction, and liquid level in open or pressurized containers. Differential pressure gauge only suitable for measuring non-aggressive media, such as the need to measure aggressive media, should be installed with appropriate isolation device. Differential pressure gauge must be used with the display instrument. According to the different output signals, differential pressure gauge is divided into A, B two types.
