The Yokogawa UT520-08 is a Dual-Digital Display Meter designed for simultaneous monitoring of two different process variables.<br />
Its primary function is to accept two independent input signals from sensors or transmitters and display their values simultaneously on a single, compact dual-display unit. This is highly effective for applications where comparing or monitoring two related parameters is necessary, such as inlet/outlet temperature, pressure and temperature, or flow and total volume.

Key Applications
This dual-display meter is ideal for:
Energy Monitoring: Displaying flow rate and totalized flow simultaneously.
Process Comparison: Showing inlet and outlet temperatures of a heat exchanger.
System Monitoring: Displaying pressure and temperature from the same process point.
Any application where space is limited and two related values need to be viewed at a glance.
