Description

The wireless differential pressure gauge is a key component of the AKS FieldPORT™ wireless monitoring systems. The Differential Pressure Fie d Unit is a complete, integrated differential pressure sensor, signal conditioner and RF transceiver with self-contained power operating in the 902 MHz to 928 MHz ISM Incense-free band.

The Differential Pressure Field Unit may be operated in anyone of four modes:

• Differential Pressure
• Orifice Flow
• Open Channel Flow
• Level

(See configuration options below)

Data from the sensor are transmitted to a Base Radio Logger for centralized monitoring and data acquisition. You may specify updates between once per second and once per minute based on haw frequently the process is monitored and how often the data is transmitted.
