At Mid-West Instrument, we manufacture high-accuracy bellows-type differential pressure gauges with built-in features that support safe, long-term operation. One of the most important components in our bellows-style design is the bidirectional pressure relief valve. This valve is critical to protecting both the gauge and the surrounding system from damage caused by overpressure in either direction. […]

At Mid-West Instrument, we manufacture high-accuracy differential pressure gauges for critical measurement applications, including flow monitoring. In many of these flow applications, a standard linear scale is not sufficient because of the mathematical relationship between flow rate and differential pressure. To address this, we offer gauges with square root dials. These specialized dials are designed […]
