Application for Rheotherm and RheoVac Instruments

Flow Measurement Instruments

Rheotherm Flow Instruments – Model 210R

The Rheotherm Model 210R flow meter is an advanced precision low flow meter used across industries to measure the flow of liquids, gases, and homogeneous slurries. The Model 210R offers the same accuracy and performance as the Model 210 and comes with remote electronics that can be located up to 200 feet from the sensor. This flexibility makes 210R ideal for applications with space constraints and hazardous environments.

Whether you are measuring ultra-low flows in chemical processing facilities or specialized applications in hazardous or radioactive environments, the Model 210R offers precision, reliability, and long-term durability. It provides accurate flow measurements down to 1 gallon per year for liquids and 30 SCCM for gases, and is compatible with a wide range of viscous, caustic, and corrosive fluids.

Features of Rheotherm Model 210R Flow Meter

The Rheotherm Model 210R shares many of the features of the Model 210, with a few key enhancements for applications with typical requirements.

Remote Electronics Flexibility: The Model 210R’s electronics can be mounted up to 200 feet away from the sensor, allowing for installation in environments that are too harsh or dangerous for standard electronics. These remote electronics can be housed in a NEMA 7 explosion-proof enclosure or in a panel mount or lab-style enclosure, providing a range of options to suit the needs of your application.
Superior Chemical Compatibility: Just like the Model 210, this precision low flow meter features durable construction and is compatible with most process liquids and gases, including those found in industries like pharmaceuticals, chemical processing, and wastewater treatment.
Minimal Maintenance & High Reliability: These precision low-flow meters have no moving parts, which ensures long-term reliability with minimal maintenance requirements. The flow meter offers minimal pressure drop and stable performance, even under challenging conditions.
Enhanced Temperature Compensation: 210R utilizes advanced temperature compensation technology to ensure precise flow measurement, even when operating in fluctuating conditions. This feature helps prevent measurement drift and maintains accurate results over time.
Advanced Self-Diagnostics: Equipped with sophisticated self-diagnostics, the Model 210R continuously monitors system performance, detects faults, identifies flow inconsistencies, and helps prevent sensor drift, ensuring reliable operation.
Multiple Calibration Data Storage: The Rheotherm flow instrument can store up to four calibrations for liquids or gases, making it adaptable for different process fluids.
Field Adjustable Calibration: Like the Model 210, 210R provides on-site calibration adjustments, ensuring customizability to meet your specific process requirements.

Applications

These FM-approved flow meters are suited for applications requiring remote electronics and are versatile to operate in challenging environments. Some key applications include:

Radioactive Environments: The Model 210R is designed for use in radioactive environments, where the sensor can be located in the radioactive zone, while the electronics are placed remotely, up to 200 feet away in a safe area. We offer both low-radiation and high-radiation options for such applications.
Hazardous Locations: With FM-approved intrinsically safe sensors and explosion-proof enclosures, 210R is perfect for hazardous and explosive environments, where safety is paramount.
Space-Constrained Installations: The Model 210R’s remote electronics provides an excellent solution for limited space. This ensures optimal performance even in tight or hot environments.
High-Temperature Applications: 210R may be a better option for certain high-temperature applications (over 250°F) as the remote electronics reduce the impact of elevated temperature on the components and display.
Large Line Size Measurements: This flow meter is also ideal for large line sizes where an inline probe is required, and the operating temperature exceeds the limits for standard integral units.
Sanitary & High-Purity Applications: Like the Model 210, this flow meter is suitable for sanitary applications, including pharmaceuticals, food, and beverage production, where hygiene and contamination control are crucial.
