When in the <b>Pump Startup</b>, <b>Operating</b> or <b>Backwash</b> state, each tank pressure is briefly shown on the LCD in psi. If the value is not valid, <tt>Fault</tt> is shown in place of a pressure value. | When in the <b>Pump Startup</b>, <b>Operating</b> or <b>Backwash</b> state, each tank pressure is briefly shown on the LCD in psi.

Output water flow is monitored by a paddle wheel flow meter that generates a sine wave with a frequency proportional to the flow rate. A flow "transmitter" (GF Signet 8512) translates that analog output from the flow meter into a 4-20 mA signal proportional to the flow rate. | Output water flow is monitored by a paddle wheel flow meter that generates a sine wave with a frequency proportional to the flow rate.
