Meriam

Meriam, also known as Meriam Process Technologies, is a US-based manufacturer of pressure and flow measurement instruments. The company is recognized for its manometers — including U-tube, well-type, and inclined-tube designs — and laminar flow elements (LFE) used as primary flow measurement standards for gases. Meriam instruments provide reliable, liquid-column-based pressure measurement solutions widely applied in calibration, process testing, and HVAC environments.

Meriam's laminar flow elements deliver primary-standard-level accuracy traceable to national standards, making them a trusted reference in gas flow calibration laboratories and aerospace test facilities. Their product line also encompasses calibration accessories and general pressure measurement tools suited for both laboratory and field applications.
