• Compact and lightweight, easy to install

• Hazardous area approvals

• Converter electronics to suit application

Repeatable and accurate

Thermo Scientific Sarasota liquid density meters fulfill demanding application requirements within the oil and gas, petrochemical, and chemical industries. Specific applications include:

• Blending

• Product identification

• Interface detection

• Dilution measurement

• Process/quality control

• SG measurement

• Process efficiency

• Product consistency

• Volumetric to mass flow metering systems

These devices utilize the proven vibrating element design which is widely accepted as the most accurate method of continuous, online density measurement. In fact, our twin tube design is inherently more stable than single tube technology, and an integral, high grade PT100 temperature element within the instrument allows compensation of the density meter for temperature effect and may be used for compensation to reference conditions. Our meters detect any variation of process constituents or final product quality in near real-time to improve productivity, minimize product waste and reduce costs when compared to sampling methods.

Compact and easy-to-install

Compact and lightweight, the density meters tolerate significant plant vibration and can be installed directly into existing pipe work 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 your products moving at optimal speed.

Durable and functional

A choice of sensor materials is offered for wetted parts, including Hastelloy® C276 for improved corrosion resistance and stainless steel for general industrial use. With hazardous area approvals and secondary containment on all models, these instruments withstand tough industrial environments to ensure a significant return on investment.

The Sarasota FD910 for Industrial Applications

The Sarasota FD910 meets the demands of general process monitoring and control applications across a vast number of industries. With its stainless steel construction, the Sarasota FD910 industrial density meter is best suited to those general process applications that do not require the specialist materials offered by the other models in the range.

The Sarasota FD950 for Chemical Applications

The wetted parts of the Sarasota FD950 are made of Hastelloy C276 making it the most corrosion resistant option of the range. It is ideal for aggressive applications in the petrochemical, chemical, and pharmaceutical industries.

Density converter electronics

The Sarasota liquid density meters can provide output variables such as specific gravity, % concentration, °Brix, °API, °Baume, line density or referred density, when used in conjunction with a Sarasota density converter. The Thermo Scientific™ Sarasota HME900 integral, field-mounted density converter option provides a direct HART-compatible 4-20 mA output, whereas the Thermo Scientific™ Sarasota CM515 remote, panel-mounted computer provides a local display and a variety of operator selectable outputs that feed into a plant’s optimization system.

Calibration and service

Calibration of the Sarasota liquid density meters is conducted in-house on a calibration rig that is traceable to national standards. Supporting documentation is available including a traceable equipment list. For most applications, installation is straightforward, on-site calibrations are generally unnecessary and the instruments are usually maintenance free. However, our dedicated service team offers commissioning, maintenance and repair services for our liquid density meters and associated electronics. On-site visits, in-house repairs and maintenance contracts can be arranged as required.
