Wireless Flow Totalizer with Display

The ModQ Sentry is a C1D1 Intrinsically Safe Wireless Flow Totalizer that is a plug replacement for Totalizer Heads such as the Cameron NuFlo MCII, MCIII, Blanchett, and Kimray.

The ModQ works with the SignalFire Wireless Gateways which allow a  Modbus RTU or Modbus TCP Interface to SCADA Host, RTU. This allows the ModQ to connect wirelessly to a site RTU.
