How it Works

INTEGRATED FLOW METERS

DP Flow measurement can be utilized to optimize many aspects of a process, including product consistency, custody transfer, production efficiency and safety applications. Daniel and Rosemount DP flow measurement solutions are versatile, easy to install and troubleshoot. Devices are suitable for use in a wide range of fluids including corrosive liquids, slurries, saturated or superheated steam, gas and many other process applications.

ORIFICE FITTINGS

Orifice fittings are widely used in the oil and gas industry to measure gas, liquid and even fluids with a small amount of second phase. Common components of an orifice measurement system include the fitting, the plate and the plate carrier. The plate along with the adjacent part of the pipe and the pressure connections constitute the primary element. Cost-effective and straightforward, this technology offers high accuracy without calibration and is easy-to-use and troubleshoot.

PRIMARY ELEMENTS

There are many kinds of primary elements that provide options for most line sizes and flow rates. These options include standard and conditioning orifice plates, averaging pitot tubes, Venturi tubes, flow nozzles, cones and wedges. With many mounting configurations, these primary elements also feature tighter process control due to low signal noise, high accuracy, low maintenance cost and integral temperature sensor options for reduced process penetrations.

FLOW CALCULATIONS

DP Flow is proportional to the square root of differential pressure, making pressure a critical component of DP Flow calculations. Other factors that influence the mass flow include: density, viscosity, temperature, pipe diameter and fluid type. In many industrial processes, numerous measurement and control devices are used to ensure accurate liquid, gas and steam flow rates for increased safety, productivity and cost-efficiency.

FLOWMETER OUTPUTS

For best-in-class performance, MultiVariable™ transmitters measure static pressure, differential pressure and temperature and can be engineered to calculate flow. Flow meters can provide process variable outputs as well as calculated real-time mass, volumetric or energy flow. Calculated flow output delivers accurate, reliable information quickly for improved process performance.

APPLICATIONS
