Product Information

The ChlorineTrak™ 760S has been specifically designed to perform as an accurate and cost-effective mass flow measurement solution for chlorine injection processes found in typical waste-water treatment applications.

Given the corrosive nature of chlorine gas (particularly in the presence of moisture), finding an economical measurement solution posed a great challenge to the industry. To answer this challenge, Sierra has designed a flow body manufactured from Kynar® polyvinylidene fluoride resin (PVDF). This material offers excellent corrosion and chemical resistance at both ambient and elevated temperatures. PVDF is also inherently stable, mechanically tough, and abrasion and flame resistant.

The 760S’s flow sensor utilizes a 6” Hastelloy® C-127 probe and 1” Swagelok® Hastelloy® NPT compression fitting to mate with the Kynar® PVDF flow body. Hastelloy C is highly resistant to pitting and crevice corrosion and is used extensively in the most corrosive environments.

With its sizable turndown (100:1) and a mass flow reading that requires no pressure or temperature compensation, Sierra’s highly repeatable and stable sensor technology offers an accurate solution for chlorine flow measurement at an economical price. Sierra’s Smart Interface™ software guides you through a procedure to fully validate instrument performance and allows for field adjustment of critical flow meter settings.

Our digital communications solutions offer engineers and systems integrators, full industrial system integration and networking capability with Sierra's thermal mass flow meters. Digital communications solutions include: Foundation Fieldbus, HART, Modbus RTU, and Profibus DP. This flexibility of communication features offers turnkey solutions for integration of Sierra's thermal mass flow meters into any industrial automation system or application.


Operating Principle

Sierra’s unique Steel-Trak™ sensor probe is responsible for the unsurpassed accuracy, ruggedness and reliability of Sierra industrial flow meters. The immersible Steel-Trak sensor consists of two sensing elements–a velocity sensor and a temperature sensor that automatically corrects for changes in gas temperature.

When power is applied to the flow meter, the transducer electronics heats the velocity sensor to a constant temperature differential above the gas temperature and measures the cooling effect of the gas flow. The electrical power required to maintain a constant temperature differential is directly proportional to the gas mass flow rate.

Both sensors are reference-grade platinum resistance temperature detectors (RTDs). The platinum RTD wire is wound on a rugged ceramic mandrel for strength and stability. Steel-Trak sensors are clad in a rugged, sealed 316 stainless steel encasement.
