Endress+Hauser Promass A 200 Coriolis mass flowmeter for low flow liquid dosing

High-Precision Low Flow Coriolis Measurement Solutions

In modern industrial automation, precision control over chemical additives, liquid dosing, and pharmaceutical ingredients is critical for product quality and process efficiency. The Endress+Hauser Promass A 200 Coriolis Mass Flowmeter provides an accurate, dependable solution designed tailored for micro-flow and low flow applications. As an experienced distributor of industrial process control instruments, we supply authentic Endress+Hauser field instruments to meet strict global engineering standards across diverse process sectors.

The Promass A 200 sensor utilizes a high-frequency, self-drainable single-tube system supported by an internal balancing mechanism. This advanced mechanical design isolates the measuring element from external pipe vibrations, pressure fluctuations, and plant noise, enabling highly stable, repeatable measurement down to fractions of a gram per minute. Whether managing delicate active pharmaceutical ingredients (APIs), high-pressure catalysts, or high-purity solvents, the Promass A 200 delivers uncompromised accuracy across changing fluid properties.

Cost-Effective Loop-Powered Two-Wire Technology

Traditionally, high-accuracy Coriolis mass flowmeters required four-wire electrical architecture, adding substantial wiring complexity and installation costs. The Promass A 200 incorporates genuine two-wire loop-powered technology (4-20 mA HART), making it an ideal choice for both greenfield projects and direct retrofitting into existing loop-powered instrumentation networks.

By eliminating dedicated power cabling, engineering teams significantly cut installation time, cabinet space requirements, and total operational expenditures. The system includes an intrinsically safe dual-compartment transmitter housing designed for extreme durability in harsh offshore, chemical, or dusty industrial environments.

Multivariable Measurement and Process Reliability

The Promass A 200 is not merely a mass flow device; it simultaneously captures multiple process variables through a single inline installation point, including:

  • Mass Flow Rate

  • Volume Flow Rate

  • Fluid Density & Reference Density

  • Process Temperature

This multivariable capability reduces the need for secondary sensors, saving valve and pipe space in modular skid systems and chemical dosing racks. Furthermore, wetted materials such as Stainless Steel 1.4435 (316L) and Alloy C22 offer exceptional corrosion resistance against aggressive chemicals, acids, and organic solvents.

Advanced Diagnostics with Heartbeat Technology

To maintain maximum plant uptime and comply with ISO 9001 quality management regulations, the Promass A 200 integrates Heartbeat Technology. This built-in diagnostic and verification feature continuously monitors device health and measuring performance without interrupting ongoing production processes. Operators can run automated verification protocols directly via the local display or digital fieldbus communication (HART, PROFIBUS PA, FOUNDATION Fieldbus), receiving clear, traceable safety reports for preventive maintenance schedules and regulatory audits.
