The Series AFS Air Flow Sensor is a differential pressure air velocity sensor designed to measure average air velocities in VAV terminal units and HVAC ductwork. It has an aero-dynamic elliptical shape resulting in a minimum pressure drop and amplified differential pressure signals which allow accurate measurement of air velocities from 300 fpm to 5000 fpm (1.5 m/s to 20 m/s). It includes multiple sensing points aligned in line grooves to measure total and static pressure. It is easy to install and cost effective. Series AFS Airflow Sensors are perfect for VAV Retrofits. The AFS is a differential pressure air velocity sensor designed to measure average air velocities in VAV terminal units and HVAC ductwork. Installation:Easy / External or Self-Supported Accuracy:1% Design:Aero-Dynamic Elliptical Shape Ideal for:VAV Retrofits

The Series JFM-S FloSen® Airflow Measuring Stations provide accurate, repeatable measurement of air movement in HVAC ducts. The Probes patented ellipticallyshaped sensor design with improved aerodynamic characteristics outperforms more traditional devices, and overcomes loss of accuracy caused by fluid separation at the sensor body. It is designed to maintain a constant parallel airflow pattern over the static sensing ports for more accurate, steady signals under all duct conditions. The elimination of separation results in a stabilized static pressure signal, helping to eliminate “hunting” during fan control. Installation:Easy / External or Self-Supported Accuracy:1% Design:Aero-Dynamic Elliptical Shape Velocity Range:300 - 5000 FPM (1.5 - 25 m/s) Duct Shape:Round / Square / Rectangular Probe Material:PVC or Aluminum Probe Length:8 - 120" (200 - 3000 mm) Turn-Down Ratio:17:1 Station Material:14 gauge Galvanized Steel

The Series AFA Siren™ Air Flow Alarm is an airflow monitor designed to provide visual and audible indications for decreases in airflow. Its color changing LED's provide vibrant visual indication of the operating status of the unit. A crisp and clear audible alarm will sound when airflow decreases below the designated set point. The Siren™ offers multiple mounting options including bracket mounting and interlocking strips. The unit can be powered through the 6-position terminal connection or by use of a power adapter. The Siren™ offers the ability to customize the minimum velocity set point should there be a need for a set point greater than the standard 80% of operational velocity. All units come standard with a night set back option for those who are energy conscious. The Siren also fulfills the exhaust alarm requirement needed to be in compliance with NSF/ANSI Standard 49. A quick installation process, one-touch calibration, and one-touch reset make for an easy set up and easy use. Status Indication:High Visibility Installation:Quick and Simple Night Set Back:Standard Alarm:Audible Mounting Options:Multiple

The Series VTP Multi Range Air Velocity Transmitter can simultaneously display and output Air Velocity, Temperature and Pressure (optional). This is the first product to combine all 3 variables in one transmitter making the VTP an exceptional option for multi-variable measuring. The VTP utilizes an industrial 316 Stainless Steel armored RTD sensor as the thermal air velocity measuring component. Using a fully protected 316 SS sensor drastically extends the life of the air velocity sensor and also makes it insensitive to water, dust or corrosion. The VTP comes standard with a LCD and can simultaneously display air velocity, temperature, and pressure. The VTP is easily configured or adjusted in the field with the digital display and keypad. The Air Velocity Range and Pressure Range are both field adjustable as well as units of measure. Other adjustable parameters include signal dampening and low velocity cut off point. Design:316 SS Armored Sensing Element and Probe Design:Simultaneous Display and Output of Air Velocity, Temperature and Pressure Adjustable Range:0-200 fpm to 0-4000 fpm (5 m/s to 20 m/s) Display:CFM or M3/h and totalizes Agency Approvals:RoHS Probe Length:6 - 36 " (152 - 914 mm) Pressure Range:0-1" w.c. (250 Pa) up to 0-10" w.c. (2.5 kPa) Output:two or three 4-20 mA or MODBUS

The Series JFM-P FloSen® Airflow Meassuring Probes provide accurate, repeatable measurement of air movement in HVAC ducts. Its patented elliptically-shaped sensor design with improved aerodynamic characteristics outperforms more traditional devices, and overcomes loss of accuracy caused by fluid separation at the sensor body. It is designed to maintain a constant parallel airflow pattern over the static sensing ports for more accurate, steady signals under all duct conditions. The elimination of separation results in a stabilized static pressure signal, helping to eliminate “hunting” during fan control. FloSen® Airflow Probes utilize a unique in-line groove for total pressure sensing and dual ports for static pressure sensing which produces a higher differential pressure for very low velocity measurements. The total and static pressure measuring points are distributed for equal-area averaging of flows resulting in improved accuracy and reliability.
