With world-class brands, deep application expertise, broad industry experience, and an extensive local presence, ERNIEGRAVES is positioned to deliver trusted industrial flow, level, pressure, and temperature automation solutions. Our well-trained sales, engineering, service and warehouse professionals are committed to providing the highest levels of support and welcome the opportunity to meet all of your measurement and control needs.

The ERNIEGRAVES team always views customer requests “from the same side of the table” as each customer: they will own the request until they can match the requirement with the best fit of technology, performance, price, and delivery. Equally, ERNIEGRAVES staff frequently provides after-sale training to ensure that each piece of equipment is used and maintained properly.
