Combining a Doppler velocity flow sensor and a hydrostatic level sensor with our advanced Multilog IS data logger, Multilog IS Flow is our complete 'plug and play' flow monitoring system.

Both rugged enough for permanent flow surveys and portable for short-term use, Multilog IS Flow is intrinsically safe, UKCA/ATEX Zone 1 certified and IP68 rated, making it safe for use in hazardous sewer environments.

Multilog IS Flow is equipped with our advanced modem and connects reliably via LTE-M or NBIoT with 2G fallback for consistent and dependable data telemetry.

The system is fitted with two long-life lithium batteries, providing power for both the logger and the sensors for five years (depending on sample transmission rate).  The ATEX-certified battery pack is connected to the data logger using Mil. Spec. connectors and can be replaced on site in seconds.
