Through-flow meters
9 Oct 2014
M+W Instruments, an operational business unit of Bronkhorst, specialises in the production of direct measurement, thermal mass flow meters and controllers for virtually every type of gas.
Based on many years of experience and dedication to continuous research and development, the company’s main focus is the production of high quality instrumentation based upon the Constant Temperature Anemometry (CTA) principle with flow rates ranging between 0.1…6000 ln/min Air equivalent.
Multi-functional approach
A company based in South Wales specialising in the design, installation and maintenance of gas systems was asked to install the medical gas network in a new hospital.
An approach was made to Bronkhorst for the supply of gas meters which could then be communication-linked to the building maintenance system.
Bronkhorst offered its M+W MASS-STREAMTM D-6360 & D-6370 instruments with integrated multi-functional displays to fulfil both the accuracy and reliability requirements.
As a result of its through-flow measurement CTA technology, the instruments offered the additional benefits of no risk of clogging, no wear as there are no moving parts, minimal obstruction to the flow of the gas and hence ultra-low pressure drop, all based upon the fact that the instrument body is essentially a straight length of tube.
In addition to the local integrated displays the instruments also feature both 4…20 mA and RS232 output signals ensuring integration with the Building Management System (BMS) for real time continuous data logging and remote alarming should the gas supply enter low- or high-flow status for any given event.
Furthermore, as a double fail-safe, the instrument offers both on-board flow totalisation and further hi/lo alarms.
According to Bronkhorst, The installation of M+W instruments at the hospital application provided the following benefits to the client:
- Separated invoicing for hospital/clinic/laboratory departments sharing the same source of medical gas
- Monitoring and acquisition of consumption data
- Leak detection within gas line, safety vent and medical gas source
