AVFS-2

The Dwyer Automatic Flow Switch AVFS-2 FTAVFS-2 is a versatile and reliable flow switching solution designed for various applications where water or other liquids need to be monitored for flow. This switch is engineered with precision and durability, ensuring long-lasting performance in demanding environments.

The AVFS-2 FTAVFS-2 features a unique, positive-displacement vane design that provides accurate flow sensing capabilities. This design allows the switch to operate effectively even in applications with entrained air or non-uniform flow. The switch is available in two flow ranges: 0.1 GPM to 0.4 GPM and 0.4 GPM to 1.0 GPM.

The switch housing is constructed from high-quality, corrosion-resistant materials, including a PTFE-coated stainless steel body and a Viton O-ring seal. These materials ensure the switch can withstand harsh conditions and prolong its lifespan, making it suitable for use in industrial, agricultural, or residential applications.

The AVFS-2 FTAVFS-2 is also equipped with a built-in temperature sensor that can detect temperatures between -40 F and 212 F. This sensor can be used to activate temperature alarms or control other devices based on the temperature of the liquid passing through the switch.

The switch offers multiple mounting options, allowing it to be installed in various orientations. It can be mounted on the top, bottom, or side of a pipe, and it can be used with both metallic and non-metallic pipes with diameters ranging from 0.25 inches to 1.5 inches.

The AVFS-2 FTAVFS-2 comes with a number of convenient features, including a test switch that allows users to manually operate the switch and confirm its operation. It also includes a built-in LED indicator light that illuminates when the switch is activated.

The switch is easy to install and maintain, with no external adjustments or calibration required. It operates on a 115V AC power supply and is UL and CSA listed for safety. With its robust design, versatile capabilities, and ease of use, the Dwyer Automatic Flow Switch AVFS-2 FTAVFS-2 is an excellent choice for anyone in need of a reliable and accurate flow switching solution.

The Dwyer AVFS-2 and FTAVFS-2 are two flow sensors manufactured by Dwyer Instruments. Both sensors are designed to measure the flow rate of liquids, but they have some differences that could influence your purchasing decision. Let's discuss the pros and cons of each sensor.

1. The AVFS-2 is a variable area flow sensor, which means it has a large, variable orifice that can accommodate a wide range of flow rates. This makes it suitable for applications with varying flow conditions.

2. It offers a high degree of accuracy and repeatability, making it a reliable choice for process control applications.

3. It is available in different process connections, including threaded, flanged, and welded ends, making it versatile for various process piping systems.

1. The AVFS-2 has a relatively low turndown ratio, which means it may not perform optimally in applications with large flow rate variations.

2. It requires regular maintenance to ensure accurate measurement, as the sensing element can get fouled by solid particles or buildup.

1. The FTAVFS-2 is a turbine flow sensor, which means it uses a rotating impeller to measure flow rate. It offers a high turndown ratio, making it suitable for applications with large flow rate variations.

2. It is a non-clogging design, which means it requires minimal maintenance and can handle solid particles up to a certain size.

3. It offers a fast response time, making it suitable for applications where quick measurement is essential.

1. The FTAVFS-2 may not be as accurate as other flow sensors, especially in applications with low flow rates.

2. It has a higher pressure drop than other flow sensors, which could increase the energy consumption of the system.

Both the Dwyer AVFS-2 and FTAVFS-2 have their strengths and weaknesses. The AVFS-2 is a reliable choice for applications with consistent flow conditions and a need for high accuracy. The FTAVFS-2 is a better option for applications with large flow rate variations and a need for minimal maintenance.

Based on the given information, if your application requires consistent flow conditions and high accuracy, the Dwyer AVFS-2 would be the recommended choice. However, if your application has large flow rate variations and minimal maintenance is a priority, the Dwyer FTAVFS-2 would be the better option. It's important to consider the specific requirements of your application before making a purchasing decision.
