PROtrol
Draw, Ratio & Net Rate Meter

Featuring 6 digits of bright, 7-segment LED displays, the Protrol is a rate, ratio, draw and net rate meter which is field programmable. The two inputs (A & B) each have separate scaling factors. The unit can be programmed to display: two separate ratemeters (A & B), the net rate difference of A & B, the ratio of A to B (A ÷ B) or the draw [(A – B) ÷ B]. Two assignable set points are standard with a programmable hysteresis (alarm range).
