SLA series Mass flow controller
SLA5800 Series Elastomer Sealed Thermal Mass Flow Controllers & Meters Advance and simplify your mass flow control. Models SLA5850 / SLA5851 / SLA5853 / SLA5860 / SLA5861 / SLA5863 Imagine choosing just one mass flow controller platform to handle fourteen different pressure or flow rates going into a single process. All while delivering the exact same, ultra-precise and repeatable output on the other side. That’s the advanced simplicity you get with the SLA5800 Series digital mass flow controllers and meters. The SLA5800 Series features the high accuracy, high zero stability and high repeatability you expect from the industry leader in mass flow measurement and control technology. Engineered with a superior design - and manufactured with advanced metrology and test systems - the SLA5800 digital MFC offers a better zero drift specification than competitive products. SLA5800 has been proven to maximize production uptime and reduce maintenance and machine downtime costs. Features ISO/IEC 17025 accredited SLA Series Biotech MFC offers two options packages with features created specifically to improve bioprocessing performance.

Programmable multi-gas/multi-range capabilities Advanced self-test routines and an independent diagnostic service port lets users troubleshoot or change flow conditions without removing the MFC from service

MT3809 Metal Tube Variable Area Flowmeter
Engineered to work where you need it: Choose MT3809 for all the high-pressure, high-temperature flow measurement requirements on your next project. MT3809 features a digital LCD display with local operator interface, providing valuable process outputs such as totalization and alarm signals. It also lets users make parameter changes without removing the cover, which means changes can be made even in hazardous areas.

GT1600 Glass Tube Variable Area Flowmeters
GT1600 Series glass tube variable area flowmeters have been engineered with a rugged design for long-lasting performance in low and high-flow gas and liquid applications where viewing the process is important. These versatile and economical meters are for general use in applications with moderate metering accuracy requirements — typical accuracy ranges are 1% to 10% full scale, depending on the model selected. They are ideal for purge type service, seal oil systems, bearing lubrication and cooling water indication.
