Selection Manual of PCL-M Thermal Gas Mass Flowmeter
Product Overview
The PCL-M series thermal gas mass flowmeter is designed based on the principle of thermal diffusion. This instrument uses the constant temperature difference method for accurate gas measurement. It has the advantages of small size, high degree of digitalization, easy installation and accurate measurement.
Features
■ Direct measurement of mass flow rate without temperature and pressure compensation
■ There are no flow-stopping or flow-blocking components in the measuring pipe, which will not cause pressure loss or blockage
■ Simple structure, easy to install, no high requirement for straight pipe sections
■ No mechanical transmission parts, strong and vibration-resistant
■ Wide range ratio 100:1; Large bore, low flow rate, negligible pressure loss
■ High-performance intelligent microprocessors and analog-to-digital, digital-to-analog conversion chips
■ Suitable for flow measurement of all kinds of single or mixed gases
Uses and Industries
■ Oil and gas, chemical, metallurgy, pulp and paper, food and medicine, environmental protection and other industries Measurement of biogas, gas, natural gas, liquefied gas, boiler preheating air
