Differential Pressure

differential pressureDifferential pressure flow meter: SITRANS F O

Description

Differentiall pressure measurement is a universal flow measurement for liquids, gases and vapors. Differential pressure flow meter always provide accurate results even with large bores, high temperature and extreme pressure.
Primary differential pressure devices, like SITRANS F O orifice, are standardized mechanical flow sensors according DIN EN ISO 5167 which are used for volume and mass flow measurement. The SITRANS F O orifice are suitable for non-corrosive and corrosive gases, vapors and liquids; permissible operating temperature -60 to +570 °C. The created differential pressue will be converted with the help of a differential pressure transmitter SITRANS P delta P into a proportional flow signal. For calculation of the SITRANS F O orifice to DIN EN ISO 5167 is an completed filled out questionnaire necessary.

Differntial pressure flow meter application examples: Power stations, Petrochemical industry, Chemical industry

Product Variation Request - PVR

This page explains how to order a non-standard product

Definition of PVR

Siemens offers you the possibility to customize your product. We call these applications for Product Variation Requests (PVR).

A PVR is an application for a product which is not defined within the order structure and is therefore not a selectable option within the PIA Life Cycle Portal either.

If you should be interested in a custom-designed device, then please consult your responsible sales person or send us a support request

Vortex

SITRANS FX300SITRANS FX300

Description

The SITRANS FX300 vortex flowmeter provides accurate volumetric and mass flow measurement of steam, gases and liquids as an all-in-one solution with integrated temperature and pressure compensation.
The vortex flowmeter product program consists of two types of flowmeters, a flange and a sandwich version, making Siemens unique as it covers all possible applications. The flange version is available with a single or dual converter, whereas the sandwich version is only available with a single converter. Both versions have the temperature sensor integrated and the pressure sensor as an option.
The SITRANS FX300 vortex flowmeter is available in a compact or remote version (Cable length: 5m, 10m or 15m).
This product is also available as a customized product, please see Product Variation Request (PVR).

Key applications for the SITRANS FX300 are found in supply processes (auxiliary service), Chemical industry, HVAC, Power plants, Food & beverage industry and Oil & gas industry.
