The Flat-Trak® Model 780S offers improved measurement capabilities in installations where long straight pipe runs are not available. The meter incorporates Sierra’s unique dual-plate flow conditioning element to eliminate velocity profile distortions as well as swirl and temperature stratification in the gas stream. This product reduces piping straight run requirements to as little as three upstream diameters. As a result, you save money on installation costs when compared to an orifice-plate where at least 20 upstream piping diameters are required for optimal performance.

This meter features Sierra's well known Smart Electronics Package for field-rangability, field flow-range adjustment, and field validation and diagnostics. The Model 780S has very low pressure drop, and wide turndown. The Flat-Trak™ Model 780S is hazardous area approved by CSA and CRN (Canada), FM (USA), ATEX, CE and PED (EU), IEC Ex (Australia), GOST R (Russian Federation) and Chinese Pattern Approval (China). The Model 780S is available in pipe sizes from 1/4-inch to 8-inches in a choice of NPT, Buttweld or ANSI 150 lb. flanged design (300 lb. flanges optional). Larger sizes are available upon request. Meter accuracy is +/ 1% of reading plus +/-0.5% of full scale with repeatability of +/- 0.2% of full scale.
