Milford, CT: Highly sensitive Series 1516 diaphragm-type gages are designed to detect small changes in differential pressure at high line pressure while eliminating fluid migration between high and low-pressure areas. They are particularly well suited for flow measurement when used with orifice plates, venturis, and pilot tubes. Gages offer heavy-duty anodized aluminum or stainless steel bodies and can be used at line pressures up to 1,500 psig. They provide differential pressure readings from 0-1 to 0-100 psid.
