Instrumentation &
Process Control

Mass flow controllers, pressure controllers and process instruments from Chinese makers — with the questions that decide whether a unit can go into your line asked out loud: accuracy as a share of full scale or of reading, which gases it was calibrated on, which fieldbus interfaces have passed conformance, whether an intrinsic-safety claim has a certificate number, and the export-control classification of the model.

Accuflow Mass Flow Controllers

Thermal (ACU10FA/10FD/20FD/20FDH/20FDR) and differential-pressure (ACU10FC/20FC/30FC and steam versions) mass flow controllers and meters, plus digital pressure controllers to 40 MPa, from Beijing Accuflow Technology Co., Ltd. (USCC 91110107MA002ARA9P, registered 2015-12-04, RMB 5 million). Business licence sighted: registered scope includes instrument and valve manufacture and import-export. Manuals publish ±0.5% F.S. accuracy, <0.2 s response and RS485 Modbus, Profibus, EtherCAT, Profinet and FF interfaces. Listing status: the live registry read has not been run, so no CMH Verified stamp. Published on the page: three different addresses across the licence and two websites, none clearly a production floor; the Chinese website frames the brand as the Asia-Pacific arm of an established supplier while the licence shows a domestic company held by individuals; IICT4 intrinsic safety is claimed in the manuals with no certificate number; ISO 9001 is stated as obtained in 2022 without a number or issuer; fieldbus conformance and export-control classification are not on record.
