3 Hidden Traps Of Low Flow Cutoff

Steam system operators can pay a high price for generating product that passes through a meter but fails to get measured.

Also known as low flow cutoff, those losses are a function of the turndown ratio within flow meters. The ratio — defined as the maximum measurement capability of a device compared to its minimum — dictates how wide a flow spectrum can be measured. Picture it this way: The total volume of steam produced by a system is like a parking lot. Only having enough asphalt available to apply a sealcoat to cover two-thirds of the lot is akin to the turndown ratio.
