The Kestrel 4100 Pocket Air Flow Meter was engineered specifically with the HVAC technician's many needs in mind. In addition to measuring volume air flow, this multi-functional precision instrument also measures temperature, relative humidity and dewpoint, either ambient or in any accessible airflow.

Tired of cumbersome equations to calculate the CFM? The 4100 makes it possible to determine CFM without using a calculator. For immediate and accurate air flow readings, simply enter the duct shape and dimensions, hold the 4100 in the air flow and the volume air flow readings are displayed... no calculator required! The convenient averaging mode ensures accurate CFM readings in any airflow or duct size and shape.

The Kestrel 4100 air flow meter features a powerful data logger that records 2000 sets of measurements at user-selectable time intervals (over 2 years of data can be recorded). Logged data can be reviewed with the 4100's on-screen graphing capabilities, or uploaded to a PC for in-depth review. The optional Kestrel Interface and accompanying Kestrel Communicator software makes long-term storage, in-depth analysis and detailed charting of stored data a breeze.

With on-screen customization, the 4100 can truly be personalized for every technician. Easy set-up screens allow the unit to display only relevant readings, and hide screens not relative to the job. Plus the Kestrel's User Screens group pertinent information on one easily referenced screen.

Don't let the inexpensive price tag fool you — the Kestrel 4100 is as accurate as instruments costing far more. Every Kestrel is individually calibrated to NIST-traceable standards and comes with a free Certificate of Conformity. (Individual NIST certificates and recalibration are also available.) Consider the 4100's hold and averaging functions, and it's the only instrument HVAC technicians need to perform a variety of jobs.

This all-in-one instrument is so comprehensive, accurate and innovative that it won the ACHR News Dealer Design Award for excellence in product design. "Every technician I employ will have one of these units ASAP!" said one of the Dealer Design judges.

The Kestrel 4100 Air Flow Meter is an affordable tool that is easy to carry and use, and is ideal for facilities managers, HVAC equipment sales people, home inspectors, dehumidification specialists, field installers and technicians.

The Kestrel 4200 has made HVAC technicians jobs even easier with automatic wet bulb temperature and humidity ratio readings. Of particular interest to dehumidification professionals, the Kestrel 4200 measures relative humidity, dewpoint, wet bulb temperature and heat stress index as well as the humidity ratio—and the patented dual chamber humidity sensor assures fast and accurate readings in any environment. This multi-functional precision instrument also measures: volume air flow, air velocity, barometric pressure, altitude, wind chill, heat stress index, temperature, relative humidity and dewpoint, either ambient or in any accessible airflow.

Tired of cumbersome equations to calculate the CFM? Like the 4100, the Kestrel 4200 has taken the calculations and guess-work out of air flow measurements with automatic air flow readings. For immediate and accurate air flow readings, simply enter the duct shape and dimensions, hold the 4200 in the air flow and the volume air flow readings are displayed... no calculator required! The convenient averaging mode ensures accurate CFM readings in any airflow or duct size and shape.

The Kestrel 4200 air flow meter features a powerful data logger that records 1600 sets of measurements at user-selectable time intervals (over 2 years of data can be recorded).

The new SUNX FM-200 series Digital Air Flow Sensor offers greater usability and high performance for cost and quality control applications.

The FM-200 series is a bi-directional digital flow sensor for use with air or Nitrogen gas. It offers high precision detection of ±3 % F.S and high speed response in an ultra small package, thanks to the utilizing of MEMS (Micro Electro Mechanical System) technology. The series covers a wide range of flow rates and has a wide range of I/O options standard, such as dual discrete outputs, an analog voltage output, and an external input.

Dual Digital Display: The integrated two-color dual digital display offers quick and easy verification of the sensor's operation, including flow rate, direction, and output condition.

Bi-Directional Flow Detection: The unique sensor chip of the FM-200 allows for flow sensing in both directions. The unit utilizes two temperature sensors, one on each side of a heater element, to determine the heat distribution. This concept provides accurate detection, regardless of flow direction.

Flow Rate and Flow Meter Modes: The FM-200 series not only has the ability of displaying the real time flow rate of a process, but also has a mode that will allow the unit to function as a flow meter. This is great for applications where the customer would like monitor the amount of air used or lost in their process.

Comprehensive Lineups: The FM-200 series is available in three port sizes with a total of eight flow rate ranges, from 0.5ℓ/min. through max.1000 ℓ/min. The models of the FM-200 series also boast one of the smallest package sizes in its class, with the largest model (1000 ℓ/min) being only W30 x H50 x D80mm in size.

The FM-200 is suitable for applications to control purge gas and air used on production lines, or to check seating of transparent objects or suction of objects on collection conveyors with low suction pressures.

The SUNX FM-200 series is immediately available from stock. Please contact Panasonic Electric Works Corp. of America and their authorized distributors.

Sierra Instruments' Model 640S Compressed Air Flow Meter facilitates compressor audits and enhances plant management and control strategies. Virtually immune to variations in temperature and pressure, the meter provides an accurate mass flow measurement under varying loads. Its rugged, no-moving parts design is also ideal for the high-vibration environment found in most compressor applications.

Hot-tap mounting, a variety of self-diagnostic and field-adjustment features, as well as the ability to confirm or "field-validate" the meter's calibration and measurement accuracy ensures traceability in compressor audits. The Model 640S also offers outstanding low-flow sensitivity, fast response, and low maintenance requirements for point-of-use measurement, cost-allocation and system diagnostics applications.

The microprocessor-based transmitter integrates the functions of flow measurement, flow-range adjustment, meter validation and diagnostics in a compact, explosion-proof housing. Mass flow rate and totalized flow, as well as other configuration variables, are displayed on the meter's 2 x 12 back-lit LCD panel. The programmable transmitter is easily configured via an RS-232 com port and Sierra's Smart Interface PC-based software; or via the display and membrane switches on the front panel of the device.

The Model 640S permits field-configuration of the following parameters: flow range, totalizer, alarm settings, time response, zero flow cut-off and a calibration correction factor to compensate for flow profile variations or specific application conditions. Smart Interface also furnishes a means to directly adjust the meter's calibration for a different gas composition or flow range.

Series PF2A digital flow switches provide a digital display monitoring air flow. The sensors are available both with a built-in display (rotatable) or remote panel-mountable display. Up to four sensors can be monitored by a single PF2_200 series 4-channel monitor, resulting in a 76% reduction in installation space. The sensors provide three types of outputs--NPN or PNP digital, voltage or current type analog, and cumulative pulse type outputs. The PF2A series flow switches are water resistant and conform to IP65. CE marked. Request catalog ES100-54A for more information.
