Thermal Air Flow Meter

Includes a compact versatile microprocessor based transmitter.

Thermal air 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. 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. The five models range from lab grade to heavy duty to industrial high heat. This measuring principle is based on the fact that heat is drawn from a heated body when a fluid flows past.

Thermal mass flow meters fci designs manufactures and sells a broad line of thermal mass flow meters for air and gas flow measurement. 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. In wastewater plants the thermal flow measuring principle. Thermal mass flow meter technology utilizes the relationship between flow rate and cooling effect for direct measurement of mass flow.

Thermal mass flow meters get application flexibility with sierra mass gas flow meters. The series 2440 are rugged and reliable portable thermal air velocity meters for nearly all flow measurement applications. Electronic flow sensors can prevent damage or downtime caused by wear and tear of mechanical moving parts offering a longer lifecycle than. Thermal mass flow meters measure the mass flow rate of fluids by measuring the heat conducted from a heated surface to the flowing fluid.

One sensor measures the process temperature and the other sensor is heated to a specific temperature above this. Insertion thermal mass flow meters for condensing gas environment found in digester landfill animal feeding. One sensor measures the current. The meters consist of a transmitter and probe with temperature sensors rtds located in the pins at the bottom of the probe.

Thermal flow meters are primarily used in air and gas flow measurement applications. Thermal flow measuring principle. With no moving parts and minimal invasiveness thermal flow meters provide a highly repeatable accurate low cost easy to. Air and biogas measurement e g.

A sensitive meter that can measure very low flows accurately like the fox thermal mass flow meter is the ideal instrument for this purpose. 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. This mass airflow sensor. 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.

Many mass flow controllers mfc which combine a mass flow meter electronics and a valve are.
