M-2111 Ultrasonic Flowmeter
Brand: MalemaThe M-2111 Series handles a wide range of flow rates and connection sizes.
The flow meter consists of a flow detector and a signal converter.
All the wetted parts are made of PFA.
There are no mechanical seals or moving parts.
The flow detector has non-contact transducers and a flow tube design without dead pockets.
The M-2111 is an ideal choice for use in the semiconductor Industry where extreme cleanliness and anti-corrosiveness are required.
