Portable smoke velocity detector commonly used in environmental monitoring

GR-3020 smoke flow velocity detector

Product Overview

Portable smoke velocity detector commonly used in environmental monitoringAs a portable monitoring device, it is widely used in boilers, furnaces, and various exhaust ductsSmoke flow rate, smoke flow rate, standard dry flow rateDynamic pressure, static pressure, and smoke temperatureMeasurement of parameters.

Scope of Application

Using the pitot tube method to measure gas flow velocity in pipelines,Can be used for various boilers, industrial furnaces, and exhaust ductsSmoke flow rate, smoke flow rateStandard dry flow rateDynamic pressure, static pressure, and smoke temperatureThe instrument uses imported high-precision sensors for parameter detection, with a 24-hour self drift of less than 0.15Pa, especially suitable for detecting low flow rates.

working principle

Align the pitot tube with the airflow direction, with the negative end facing away from the airflow direction. When the flue airflow passes through the positive and negative nozzles of the pitot tube, a pressure difference will be generated. The microprocessor calculates the static pressure, flow rate, and air volume based on the collected dynamic pressure, total pressure, and smoke temperature signals, and then automatically calculates the * flow rate based on the input values of atmospheric pressure, humidity, pipeline cross-sectional area, and other parameters.
