newGFM Series

GFM Series

● Equipped with a mass flow sensor.
● Supports up to 200LM in compact size.
● Low pressure loss : Low loss due to simple flow path structure.
● Flow output signal : Analog (0-5VDC).
● Drive power supply (± 15V) and signal cable are required separately.
● It can be used in a wide range of fields such as flow rate measurement with various equipment such as various pumps and vacuum equipment, environmental measurement, factory equipment, and experimental equipment.
