Technical parameters for duct air flow meter ![]() No zero shifting for duct mounted air flow meter Insertion air flow sensor for HVAC duct air flow measurementĭigital ductwork air flow indicator with display to show totalizing flow and instate flow No temperature and pressure sensor needed to calculate the air mass flow with flow unit Nm3/h, SCFM, SLM Wide range detect, turn down ratio: 1: 100, it can detect 0.5~ 120 Nm/s flow rate Thermal dissipation probe can detect low air flow rate still with good accuracyĭetect air velocity even micro air flow rate at fast response No moving parts in the air flow sensor is suitable for rugged industrial environments, long-term stability Stainless steel flow meter for wind velocity instrument with 316L wet parts material The K factor depends on the ventilator used or, when using pipe/duct measuring probes, on the size and number. The air flow is measured by determining the differential pressure and multiplying it with the K factor. Welcome to buy low price duct air flow meter from reliable China flow meter factory. The model A2G-25 air flow meter is used for measuring air flows of gaseous media in ventilation and air-conditioning applications. Air Low velocity is vital for the energy efficiency of the air distribution system. Air velocity in ducts usually has small flow rate to decrease the noise or energy consumption, low flow air duct flow indicator is demanding in ductwork air flow measurement. We sell low price air velocity flow transmitters as duct mounted air flow meter. The gas can be vent gas, stack gas or digester gas. It could be round, square, and rectangular shape ducks. The Fluke 922 airflow meter and micromanometer can be used to measure pressure drops across filters and coils, match ventilation to occupant loads, monitor indoor versus outdoor pressure relationships and manage the building envelope.SRK-100 series thermal dispersion flow meter is perfect for HVAC duct air flow measurement in large ducts, pipes, hoods, stacks. Low cost measurements of the outdoor, mixed and supply air temperatures are used along with manufacturer information. The auto power off function saves battery life. The Fluke 922 airflow meter and micromanometer has Min/Max/Average/Hold functions for easy data analysis. The bright, backlit display allows for clear viewing in all environments. In addition to duct measurement, these also include outlet. There are some sectors, particularly in the industrial field, where flow measurement plays an important role. It is also available as an anemometer and can be used in a variety of areas. Features of the Fluke 922 airflow meter and micromanometer include a user-defined duct shape and size functionality for maximum airflow accuracy.įluke 922 airflow meters and micromanometers have conveniently colored hoses which help properly diagnose pressure readings. There are different designs of flow meters. The rugged design is built for field making the meter easy to use without sacrificing performance. The Fluke 922 airflow meter and micromanometer is a powerful meter which provides differential and static pressure, air velocity and flow readings. ![]() The Digital TrueFlow Meter temporarily replaces the filter in the air handler distribution system during the airflow measurement process using a pre-cut or cut-to-fit adapter plate. Compatible with most pitot tubes, Fluke 922 airflow meters and micromanometers allow technicians to conveniently enter their duct shape and dimensions for maximum measurement accuracy. The all new Digital TrueFlow Air Handler Flow Meter provides a simple and accurate measurement of airflow through residential air handlers. The Fluke 922 airflow meter and micromanometer makes airflow measurements easy by combining pressure, air flow, and velocity into a single, rugged meter. Enter value, select unit and click on calculate. Concept of Air Velocity can be used in air conditioning, heating and ventilating work. Volume flow is usually measured in Cubic Feet per Minute (CFM).
