Endress+Hauser releases Proline Promass A Coriolis mass flow meter

September 5, 2018 – Endress+Hauser’s Promass A flow meter measures substances drop-for-drop. Promass A measures values with repeatability, even in cases where process and ambient conditions fluctuate. All of this thanks to the sensor concept. The measuring device is suited for installation, for example in modular process facilities and skids.

The Promass A sensor system is mounted on a base plate that acts as a “shock absorber,” effectively shielding the Coriolis measurement from outside interference, e.g. from pipe vibrations. Other contributing factors are the oscillation frequency of the measuring tube and its completely balanced oscillation behavior. At a specified maximum measured error of ±0.1%, high precision measurements down to 8 g/min are possible, or – if the maximum error is permitted to be ±1% – even a quantity of less than 1 g/min can be measured. A top value for Coriolis flow measurement technology.

Thanks to the variety of device options, such as nominal diameter, material, process connection, certification, transmitter type or degree of protection, Promass A can be used in numerous applications. Thanks to its design (the smallest measuring device with a nominal diameter DN 1 [1/24"]), Promass A can also be installed in extremely tight spaces, such as in skids. There are a multitude of process connections available, such as flanges, lap joint flanges, couplings, internal threads or Tri-Clamps. Promass A can be used at process temperatures between –50 to +205°C (–58 to +401°F).

The wetted parts are manufactured from stainless steel or Alloy C22 and are compliant with the requirements according to NACE MR0175/MR0103. As a result, the entire Promass A measuring system features high corrosion resistance and is suited for applications in the chemical and process industry. Since the entire sensor housing surface consists of corrosion-resistant stainless steel, Promass A is especially suited for harsh ambient conditions in the offshore and onshore sectors where aggressive, salty air is present. Process connections are available in different pressure ratings up to a maximum of 430.9 bar (6250 psi).

Other preferred fields of application for Promass A are found in the food and the life sciences industries with their hygienic or sterile environments. Users can select from various device options, such as the IP69 degree of protection or polished surfaces with a roughness (Ra) of max. 0.38 ÔÅ≠m (15 µin). The wetted parts are made of 1.4435 (316L) stainless steel in pharmaceutical quality. Various certificates and qualifications guarantee that Promass A completely fulfil industry-specific requirements, such as the suitability for the food industry (3 A, FDA, Food Contact Materials Regulation [EC] 1935/2004) and that of the pharma¬ceutical industry (FDA, USP Class VI, TSE/BSE certificate of suitability). In addition, the Promass A single-tube system is self-drainable, ensuring that no product residue is retained. This aspect is especially important in the food and life sciences industries because of their product-quality requirements.

Proline 300/500 transmitters include a web server as a standard. Using a standard Ethernet cable and a laptop – or wireless over WLAN – users have direct access to all diagnostic, configuration and device data without additional software or hardware. This enables targeted maintenance and service.
