Pulsar’s Ultrasonic Flow Monitor

Description

Pulsar’s Ultrasonic Flow Monitor is a dedicated wall mounted device for use with Pulsar’s Flow Pulse flow sensor in fixed or permanent installations. The Flow Monitor is powered using either an AC or DC power supply which then provides the Flow Pulse flow sensor with power and offers an interface via a 4-core cable.

Flow Monitor expands the capability of the Flow Pulse flow sensor by providing two relays that can be programmed as alarm (relay 1) or control (relay 2) for flow or velocity, or either relay can alternatively be programmed as a totaliser.

Flow Monitor also provides a mA output and onboard logging, including a daily total. Typical capacity is 36 days flow logging at 1 minute intervals (using optional logging software – UltraLog). Flow Monitor has an LCD display of flow rate and flow velocity (selectable), and is menu-programmable via a set of function keys.
