Thermal Air Flow Meter

Electronic flow sensors can prevent damage or downtime caused by wear and tear of mechanical moving parts offering a longer lifecycle than.

Thermal air flow meter.

Insertion thermal mass flow meters for condensing gas environment found in digester landfill animal feeding. Thermal mass flow meters also known as thermal dispersion or immersible mass flow meters comprise a family of instruments for the measurement of the total mass flow rate of a fluid primarily gases flowing through closed conduits a second type is the capillary tube type of thermal mass flow meter. The fastflo 620s is an insertion thermal mass air flow sensor designed to give you a highly reliable responsive and affordable mass flow measurement for light industrial applications where a nema 4x ip65 enclosure is acceptable. As the flow rate increases heat gets taken away from the heated sensor.

Thermal mass flow meters fci designs manufactures and sells a broad line of thermal mass flow meters for air and gas flow measurement. Measuring the very low flow rates of vent gas from oil and gas storage tanks takes a highly sensitive and accurate meter like the thermal mass flow meter by fox thermal. One sensor measures the process temperature and the other sensor is heated to a specific temperature above this. Thermal mass flow meters get application flexibility with sierra mass gas flow meters.

One sensor measures the current. A sensitive meter that can measure very low flows accurately like the fox thermal mass flow meter is the ideal instrument for this purpose. The five models range from lab grade to heavy duty to industrial high heat. Thermal flow meters are primarily used in air and gas flow measurement applications.

With north america s 1 selling thermal mass flow meter flow research boston ma customers can enjoy the many benefits of thermal technology wide turndown ratio very low pressure drop no moving parts application flexibility and a direct digital gas mass flow rate measurement. Commonly manufacturing facilities rely on flow sensors to monitor varied types of media from water oils and coolants to gases like compressed air argon nitrogen or other aggressive media. The meters consist of a transmitter and probe with temperature sensors rtds located in the pins at the bottom of the probe. Thermal mass flow meter technology utilizes the relationship between flow rate and cooling effect for direct measurement of mass flow.

Since a flowing fluid removes a known quantity of heat as it passes the temperature difference between the heated sensor and the flow stream is directly proportional to the mass flow rate. Includes a compact versatile microprocessor based transmitter. With no moving parts and minimal invasiveness thermal flow meters provide a highly repeatable accurate low cost easy to. Many mass flow controllers mfc which combine a mass flow meter electronics and a valve are.

This mass airflow sensor. A thermal flowmeter contains two pt100 temperature sensors for this purpose. This measuring principle is based on the fact that heat is drawn from a heated body when a fluid flows past. Air and biogas measurement e g.
