Product Description

Product Description

Rosemount 305 Integral Manifold Three Valve 3 Way Manifold for Pressure Transmitter

The Rosemount 305 Integral Manifold attaches directly to the patented Rosemount Coplanar™ transmitter, eliminating the need for a flange. This lightweight, premier manifold comes in a 2-, 3- and 5-valve configuration and allows instrument isolation, controlled venting and added protection from leaking to ensure measurement integrity. This product can be factory-assembled to a transmitter and leak-tested and can be used with multivariable, static and differential pressure transmitters.

Orientation Options

The manifold can be oriented either parallel with the transmitter or at a 90° angle to the transmitter. This flexibility in orientation allows for easy installation in different plant layouts and space - constrained environments. Whether the installation requires a horizontal or vertical setup, the Rosemount 305 Integral Manifold can be configured accordingly.
In conclusion, the Rosemount 305 Integral Manifold Three Valve 3 Way Manifold for Pressure Transmitter is a top - of - the - line product that offers superior performance, reliability, and flexibility. Its unique design features, high - pressure capabilities, and compatibility with various transmitters make it an ideal choice for industrial pressure measurement applications.

Company Profile

Company introduction

Main product

KeRui (weifang) Automation Equipment Co., Ltd.specializes in industrial automation instrument development, production and sales, technical services, and supportingequipment supply of specialized companies. The main products are flow meters, level meters, temperature meters,pressure meters, electrical meters, thermal intelligent meters, programmable controllers (PLC)DCS distributed control systems,and eight series of more than 1,000 specifications. Its products and technologies are widely used in electric power, metallurgy, petrochemicals, environmental protection, plastics, food, printing, tobacco,textile, dyeing, and other felds.

Valve Positioner: A valve positioner is a crucial control device that precisely regulates the position of control valves in industrial processes. It receives control signals from a controller and compares them with the actual valve position.

Flowmeter: A flowmeter is an instrument designed to measure the flow rate of liquids, gases, or steam within a pipeline or channel. 

Transmitter: A  transmitter is a device that senses a physical parameter, like pressure, temperature, or level, and converts it into a standardized output signal, usually 4 - 20 mA DC or digital signals.
