In the field of industrial flow measurement, orifice flow meters, as classic and reliable measurement devices, are widely used in the petroleum, chemical, and power industries. For users, understanding the products of orifice flow meter manufacturers and their accompanying user manuals is crucial. This not only helps with the correct installation and use of the equipment but also ensures the accuracy of measurement data and the long-term stable operation of the equipment. This article will detail the various user manuals provided by orifice flow meter manufacturers to help users better understand and operate this important equipment.

1. Basic Principles and Structure of Orifice Flow Meters

Before delving into user manuals, it is necessary to briefly review the basic principles and structure of orifice flow meters. Orifice flow meters calculate flow rate by measuring the pressure difference before and after the orifice plate. Its core components include the orifice plate, differential pressure transmitter, and flow calculator. The orifice plate is usually installed in a pipe; when fluid passes through the orifice plate, a pressure difference is generated before and after the orifice plate. The differential pressure transmitter converts this pressure difference signal into an electrical signal, and the flow calculator calculates the flow rate based on this signal.
