① Regardless of whether the flowmeter is installed vertically or horizontally, keep the flowmeter in a horizontal state. Insertion type thermal gas mass flow meter installation: Table 4: Thermal Gas Mass Flow Meter Model Selection Model Table 2: Insertion Thermal Gas Mass Flow Meter Sizing Table 3: Common Use Gas Maximum Range Standard Insertion, Hot-tapped Insertion and FlangedĬarbon Steel, Stainless Steel,Plastic etc.Ĥ lines LCD Mass flow, Volume flow in standard condition, Flow totalizer, Date and Time, Working time, and Velocity, etc. Remote type:220VAC,Power consumption ≤19WĤ-20mA(optoelectronic isolation,maximum load 500Ω),Pulse RS485(optoelectronic isolation) and HARTġ-2 line Relay, Normally Open state, 10A/220V/AC or 5A/30V/DC Sensor:-40~+220 degC Transmitter:-20~+45 degCĬompact type: 24VDC or 220VAC, Power consumption ≤18W Table 1: Insertion Thermal Gas Mass Flow Meter Parameter Measuring Medium (11) Support multiple communication methods, such as RS485 communication, MODBUS protocol, etc., which can realize factory automation and integration (10) Plug-in installation method, installation and maintenance without stopping production, easy to use and maintain If the density is constant in the standard state (that is, the composition is unchanged), it is similar to a mass flow meter (9) When measuring the gas flow, it is often expressed in the volume flow unit under the standard state, and the medium temperature/pressure change hardly affects the measured value. (8) No pressure loss or very small pressure loss. It has good seismic performance and high measurement reliability (7) The sensor has no moving parts and pressure sensing parts, and is not affected by vibration on the measurement accuracy. ![]() ![]() (6)Suitable for all kinds of single or mixed gas flow measurement Could measure gas with flow velocity from 100Nm/s to 0.1Nm/s, which can be used for gas leak detection (5)Easy to design and select, easy to install and use (4)Very sensitive for low flow rate measurement (3)Direct mass flow measurement without temperature and pressure compensation (2)Large diameter, low flow rate, negligible pressure loss Insertion type thermal gas mass flow meter advantanges :
