Measurement Instrumentation

The rigorous demands of your process operations require you to have reliable, accurate instruments that give you the measurements you need. Control Associates and its instrumentation division Pro-Tech Solutions deliver field-proven technologies and solutions from market leading manufacturers like Emerson with their world class Rosemount™ and Micro Motion™ instruments that can handle the toughest measurement conditions or analytical challenges enabling you to maximize the performance, profitability and safety of your plant.

Density & Viscosity

Density & Viscosity Meters

Density and viscosity meters provide critical process measurements of liquids and gases. Micro Motion meters are based on a vibrating-element principle whereby vibration frequency is inversely proportional to fluid density, yet each has a unique design to optimize performance for the desired measurement. The viscosity meters build on the same vibrating-element principle while also measuring additional characteristics of the frequency signal.

Rosemount™ Flow Meters

Flow Measurement is the process of measuring fluid in your plant or industry. You can measure flow through a variety of different Rosemount devices such as magnetic, vortex and differential pressure flow meters.

Magnetic flow meters are often selected because they are obstructionless, cost-effective for aggressive chemicals and slurries and provide highly accurate volumetric flow measurement. A range of liner materials, electrode options and line sizes accommodate a wide variety of process applications. Additionally, magnetic flowmeters can measure fluids bi-directionally, are effective for both very low and high volume flow rates, and are immune to changes in process variables.

Vortex flow meters offer many advantages for flow measurement including easy installation without impulse lines, no moving parts to maintain or repair, less leak potential and a wide flow turndown range. Vortex flow meters also offer very low power consumption, allowing for use in remote areas. Additionally, vortex meters are unique in that they can accommodate liquids, gasses, steam and corrosive applications. Vortex flow meters are also able to withstand high process pressures and temperatures.

As one of the most common technologies for measuring flow, differential pressure (DP) flow has a long history of achieving high accuracy and durability. This measurement technology enables compensated flow, pressure, and temperature readings from a single flowmeter solution, in some cases eliminating the need for impulse lines. Rosemount flow meters can be delivered pre-configured, leak tested, and ready-to-install, reducing installation time and costs while increasing overall plant productivity.

Coriolis Flow Meters

The basic operation of Coriolis flow meters is based on the principles of motion mechanics. As fluid moves through a vibrating tube it is forced to accelerate as it moves toward the point of peak-amplitude vibration. Conversely, decelerating fluid moves away from the point of peak amplitude as it exits the tube. The result is a twisting reaction of the flow tube during flowing conditions as it traverses each vibration cycle.

Emerson's Micro Motion Coriolis, density and viscosity technologies deliver superior flow measurement expertise while providing customers with the confidence and insight they need to continuously improve safety and efficiency in the most critical process applications.

Rosemount™ Pressure Transmitters

With over 50 years of experience, Rosemount™ pressure instrumentation provide solutions to critical measurement challenges even in the harshest environments.

Pressure technology solutions include capacitive, piezoresistive and other sensors to provide essential process data in differential, gauge and absolute pressure applications. These sensors measure pressure, level, flow and derivatives by physically responding to the changes in process pressure, converting the physical movement into an electrical signal.

Multivariable measurement capability enhances operations by measuring static and differential pressure and temperature in a single device. With a variety of options, these devices include Ultra for Flow performance class, Callendar-Van Dusen sensor matching, extended range sensor and a selection of protocols. Multivariable transmitters allow you to limit pipe penetrations, reduce wiring costs and reduce installation time.
