Promass A Measures Substances with High-Accuracy

In the food and life sciences industries, very small measurements must be made with a high degree of accuracy.

In piping or chemical reactors, flavouring for foodstuffs, active ingredients for pharmaceuticals and corrosion-inhibiting substances in oil production are just a few example applications.

The newly developed Promass A measures such substances drop-for-drop with a precision unmatched worldwide.

Some benefits include:

  • High measuring accuracy for low flow quantities (±0.1% at a minimum of 8g/min and ±1% at a minimum of 0.8g/min)
  • Excellent measuring performance and robustness, even in case of strongly fluctuating process and ambient conditions
  • High product quality in hygienic and sterile applications thanks to self-draining single-tube system
  • Space-saving installation with compact, lightweight sensors and no inlet and outlet runs required
  • Optimal process reliability, with high corrosion resistance, developed according to IEC 61508 (SIL) and heartbeat technology for permanent self-diagnostics and device verification during operation
  • Full access to all process and diagnostic data through freely combinable I/Os, fieldbuses or WLAN

Promass A guarantees maximum robustness and precisely measured values with unparalleled repeatability. All of this thanks to the innovative sensor concept, which sets new standards in Coriolis measurement technology.

Promass A is light and compact – with no losses in performance or robustness. The measuring device is therefore ideally suited for space-saving installation, for example in modular process facilities and skids.

Maximum precision thanks to the innovative sensor concept

The Promass A sensor system is mounted on a base plate that acts as a shock absorber, effectively shielding the Coriolis measuring system from external pipe vibrations and pipe forces.

Other contributing factors are the much higher oscillation frequency of the measuring tube and its completely balanced oscillation behaviour.

At a maximum measured error of ±0.1%, measurements down to 8g/min are possible, or if the error is permitted to be max. ±1% even a quantity of less than 1g/min.

The device design – robust and industry-optimised

Due to the high corrosion resistance (stainless steel, Alloy C22; NACE MR0175/MR0103), Promass A is ideally suitable for process applications, and especially for offshore and onshore areas with aggressive, salty air.

Other preferred applications are found in the food and life sciences industries with hygienic or sterile environments. This is ensured by various certificates and approvals (3-A, FDA, EC 1935/2004; FDA, USP Class VI, TSE/BSE) as well as stainless steel in pharmaceutical quality.

Transmitters for seamless system integration

Various transmitters are available for Promass A: Proline 200 (two-wire device), Proline 300 (four-wire device) or Proline 500 (remote version). They allow simultaneous measurement of mass flow, volume flow, density, concentration and temperature.

Access to measurement and diagnostic data is possible at any time thanks to numerous fieldbuses (EtherNet/IP, Modbus RS485, PROFIBUS DP, PROFINET, FOUNDATION Fieldbus, HART, WirelessHart) as well as freely combinable I/Os and WLAN (web server).

Heartbeat technology for maximum operational safety

Heartbeat technology is a a testing function which is integrated into all Proline measuring devices and enables permanent self-diagnostics as well as a TÜV-attested, metrologically traceable device verification without process interruption.

All of this reduces complexity and hazards in a plant and increases its reliability and availability. Since the Promass A measuring system has been developed in accordance with IEC 61508 (SIL), it is also preferred for use in safety-related applications.
