CAT.No.CBM102E-7

Monitors air and nitrogen flows.

Mass Flow Monitor
Wide range and low pressure loss at competitive price

1. Boasts an exceptionally wide ﬂow range〔10 to 600 (15mm), 135 to 8000 (50mm) L/min (normal)〕and rangeability 1:60 noother meter can match. Accurate detection capability that extends to extremely low ﬂowrates makes it ideal, not only to measure
air consumption but also to locate air leaking spot.
2. Thanks to the thermal dispersion principle of operation to detect mass ﬂow, it requires no corrections
for temperature and pressure. It directly indicates ﬂowrate under normal
operating conditions (at 0℃, 1 atm), which means most cost eﬀective.
3. Besides total , cumuletive total and instantaneous ﬂowrate (an hour every share) ,the display shows Yen equivalent an ideal for utility ﬂowrate from an energy saving
point of view.
4. The sensor element is durable to dust, mist, etc. because it is protected bystainless sheathed pipe.
