Dwyer DFMT2 Series Digital Paddlewheel Flow Transmitter is a two-piece digital flow transmitter that provides instantaneous, as well as totalizing flow monitoring. The two-piece design allows the user to separate the control panel from the application, making it ideal for industrial use in reverse osmosis water purifying systems and any other applications where space is limited.
The large backlit display makes navigating through the menu structure simple. The Series DFMT2 uses high accuracy, industry-proven paddlewheel technology, offers a user-selectable 4 to 20 mA or pulse output, and has a corrosion-resistant PVDF sensor giving it a long operation life. Users can reset the totalizer at any time and set a security password protecting the system settings from unauthorized changes.
