Metaval’s Differential Pressure Gauges with Bellow or Diaphragm sensing elements are designed for reliable and precise differential pressure measurement across filters, pumps, and fluid circuits. The instrument uses a force-balanced mechanism with dual sensing elements, making it ideal for monitoring pressure drop without compromising accuracy or durability — even in challenging process environments.
