Flow Sensor Offers Versatile Connectivity

By Mat Dirjish

AW-Lake Company’s EDGE Flow Sensor offers optional Bluetooth for connecting to flow meters requiring an analog, pulse, or Modbus signal to a PLC or other control system. Reportedly, the sensors easily mount on a plethora of meters including AW-Lake Gear Meters and Turbine Flow Meters, The flow sensor outputs a frequency, current, or analog signal that promises more installation flexibility, especially when unsure of readout equipment or a control room interface.

With the ability to force the sensor to output a frequency or analog signal, connections to a user interface are verifiable without the need to run fluid flow.  The sensor offers three optional pulse output configurations including push/pull, sinking, and sourcing.  A Modbus output adds additional system compatibility for more advanced operations.

A Bluetooth mobile application gives users the ability to monitor and program flow meters from a smartphone. The mobile application also supports basic scaling and advanced functions, allowing for remote correction of non-linear flow meters to keep a linear analog output.

Resistant to system vibration, the sensor has no contact between the pickup nose and meter to minimize the chance of damage due to rough handling or installation. For more information, procure and peruse the Edge Flow Sensor datasheet. V
