Modbus flow totalizer for local and remote turbine meters

30 July 2018

SignalFire Wireless Telemetry has introduced the ModQ Sentry, a Modbus Flow Totalizer that interfaces with pulse-type inductive turbine (and other) flow meters to provide instantaneous flow rates, accumulated totals and status information. Units are configurable for volume and time settings and offer options to configure the K factor to match the turbine.

Powered by an internal lithium battery for standalone operations or an external 6 – 36VDC power source, the ModQ Sentry provides a local display along with a Modbus RS485 data port to integrate with PLC/SCADA and DCS systems. The unit maintains an internal thirty-day log of daily flow totals for historical analysis or backup storage.

The ModQ is pending Class 1 Division 2 certification for usage in hazardous locations.
