The Thermo Scientific Sarasota Liquid Density Meters FD910 and FD950* from HMA INSTRUMENTATION accurately measure density or density-related variables. These online continuous meters provide key information for process monitoring and control, quality control, and product interface detection. Features include measurement at process conditions, a straight-through flow path, materials to suit a range of applications, compact, lightweight, and easy-to-install, hazardous area approvals, and converter electronics to suit the application in hand.

The Thermo Scientific Sarasota Liquid Density Meters from HMA INSTRUMENTATION fulfil demanding application requirements within the oil and gas, petrochemical, and chemical industries. These density meters tolerate significant plant vibration, and can be installed directly into existing pipework without the need for upstream flow conditioning or instrument supports. Installation is quick and simple, with minimal pipeline disturbance or process downtime. The straight-through sensor offers an unobstructed flow path to ensure minimal pressure drop and higher flow rates to keep products moving at optimal speed.

*Please note: The Sarasota Liquid Density Meter FD960 has been discontinued although we continue to provide services and support for this product.
