Indicators are actuated by single or dual bellow.

Press Release Summary:



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.

Barton Offers 3" to 6" Dial-Size Indicators for the Measurement of Differential Pressure, Flow Rate and Liquid Level Applications


City of Industry, CA (Apr. 26, 2002) - Barton Instrument Systems offers a broad selection of indicators for a variety of safe working pressures and differential pressure ranges. Irrespective of their specific type, all models are actuated by Barton's rupture-proof single or dual bellow. The indicators are widely used for the measurement of differential pressure, flow rate, and liquid level applications. Features include 3", 3-1/2", 4-1/2, and 6" (76, 89, 114, and 152 mm) dial sizes, NEMA 4/IP65
rating on selected models, a wide variety of differential pressure ranges (including absolute, zero-center, and split ranges), and pulsation damping on certain models.

The indicating pointer traverses a 270-degree arc, providing excellent readability. It is driven by a precision-jeweled rotary movement that multiplies rotation of the torque tube through a gear and pinion to the pointer. The movement, which employs a thermally stable Ni-Scan-C hair spring, has a micrometer screw for convenient range adjustments. Zero/range adjustments can be made without removing the scale plate or pointer. Linearity adjustments are readily accessible after removal of the scale plate.

All indicating scales can be graduated uniformly for measurement of differential pressure or liquid level, or square root for direct reading of flow rate. Special scales can be furnished for indicating liquid level in horizontal or non-uniform tanks.

Complete product specifications are included in a colorful brochure which is available on Barton's website at www.barton-instruments.com.
