-ERVAL is just off the screen. LEVEL READING INTERVAL refers to how often the flow meter takes a level reading. LEVEL refers to the level in the flow stream.

DO/PH READING INTERVAL refers to the measurement of spe- cific aspects of the flow stream other than amount. 4220 Flow Meters support measurement of three different characteristics: temperature, pH (the relative acidity or alkalinity of a solution), and D.O., dissolved oxygen.

Note

If you are using the Isco D.O. sensor or are sensing D.O. with the YSI 600 Sonde, select as long a measurement interval as is practical for your application. The reasoning is that the D.O. sensor is turned off between measurement intervals and this turned-off period prolongs the life of the sensor.
