Basic - Flow rate Monitor / Totalizer

with alarm / pulse output

Product description

The B-Alert is a flow rate indicator and totalizer with continuous flow rate monitoring feature. It offers the facility to set one low flow rate and one high flow rate alarm value. The display shows flow rate, total, accumulated total and alarm messages. On-screen engineering units are easily configured from a comprehensive selection.

  • The B-Series is our most cost effective display but with all the benefits you may expect from a Fluidwell product: It’s durable, reliable and very easy to operate. Basic with a capital B!
  • Familiar easy operation with the Fluidwell "Know one, know them all" configuration structure, saving time, cost and aggravation.
