May 14, 2002 Indicators are used for measurement of differential pressure, flow rate, and liquid level. Dial sizes include 3, 3 1/2, 4 1/2, and 6 in. Pointer traverses 270 deg arc and is driven by precision-jeweled rotary movement that multiplies rotation of torque tube through gear and pinion to pointer. Zero/range adjustments can be made without removing scale plate or pointer. Certain models have NEMA 4/IP65 rating and pulsation damping.
