    505-1320 Series Ultrasonic Open Channel Flowmeter SECTION 3 OPERATION Modes of Operation When using the 505-1302 Open Channel Flowmeter, there are two modes of operation: flow or distance mode. • • • • • In the flow (or level) mode, the current output (4-20 mA) increases as the liquid level rises.
  • Page 17 505-1320 Series Ultrasonic Open Channel Flowmeter Indicators & Controls —Alarm Relays Outputs for Near Zone and Lost (continued) Echo are provided to activate external relays or alarms. These are separate relay packages purchased as an option. —Step Gain Switch Changes the gain of the ultra- sonic transmitter to lessen any effect due to noise or obstruction.

  • Page 18: Time Delay

    505-1320 Series Ultrasonic Open Channel Flowmeter Time Delay Increasing time delay to either 15 or 45 seconds will smooth out a jumpy output signal caused by wave action or turbu- lence. Step Gain Switch The step gain switch can be used to decrease the acoustic signal and avoid noise interference.
