Wireless Flow Transmitter SFS-WP Series AW Lake

AW Lake is corporate from the United States of America that sells some products such as Positive Displacement Meters, Turbine Flow Meters, Tricor Coriolis Flow Meters, Lake Variable Area Flow Meters, Lake Paddle Wheel Flow Meter "Flow Stat", Monitor&Controllers, Wireless / Bluetooth.
One of the products that come from the categories of Wireless / Bluetooth is the Intrinsically Safe Wireless Flow Transmitter SFS-WP Series.

Intrinsically Safe Wireless Flow Transmitter SFS-WP Series :

Ideal when adding flow meters where there is no power – no need to run wires/conduit, installs anywhere in minutes.

The SignalFire Remote Sensing System consists of nodes attached to sensors like the SFS-WP Sentinel that work in a mesh network pattern to send data via Modbus to a Gateway, where it is transferred to a PC, PLC, or another control system. Gateway Interfaces Include:

  • HART®
  • 4-20mA current loop, 1-5 Volt
  • Digital input (state, counter, totals, frequency)
  • RS-485/Modbus

Features :

  • Internal battery powers sensor and radio so no external power source is required
  • Class I Division 1 Intrinsically safe design
  • Up to 1/2 mile range
  • The wireless node configures itself within the mesh network automatically, sending flow data to the Gateway
  • Flow rate and total data available

Advantages :

Attractive ROI: Costs less than running 60 feet of wire & conduit.

Data at Your Fingertips: Wireless data transmission anywhere in the world with an Internet connection.

Up and Running in Minutes: Easy thread-in installation. A quick setup procedure allows you to have the unit working with just a few simple programming steps.

Reliable Transmission: ISM bands sustain signal strength through terrain, structures, or weather for a range of up to 1/2 mile.

Smart Technology: Wireless nodes install themselves automatically and adapt to network changes, i.e. data volume, radio transmission conditions, and power source conditions.

Long Battery Life :

  • High-capacity Lithium battery pack powers sensors and radio for years, even in low temperatures.
  • The transmitter can be configured for check-in intervals between 5 seconds to 1-hour to save battery life.

Flexible System: Add additional nodes for pressure, temperature, and level sensors on the same Gateway.
