New Modbus Flow Totalizer for Hazardous Applications


SignalFire Introduces the C1D2 Non-Incendive Modbus Flow Totalizer for Local and Remote Readout of Turbine Meters

SignalFire Wireless Telemetry introduces 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 Modbus Flow Totalizer provides a local display along with a Modbus RS485 data port to integrate with PLC/SCADA and DCS systems.  The ModQ Sentry maintains an internal thirty-day log of daily flow totals for historical analysis or backup storage.

Modbus Flow Totalizer with Pending Class 1 Division 2 Certification for Usage in Hazardous Locations

The ModQ is pending Class 1 Division 2 certification for usage in hazardous locations.  Packaged in a high-strength, polycarbonate housing rated NEMA 4X, the units are weathertight and rugged to withstand demanding outdoor environments.  Easy to configure with local LCD and push buttons (or by using the SignalFire user-friendly ToolKit), the ModQ is ideal for data management of turbine flow meters in new and retrofit installations for a variety of industrial applications such as oil & gas, metals & mining, water & wastewater, chemical, power, food & beverage, pulp & paper, aerospace, and pharmaceutical.
