Product catalog summary
Introduction
The TGF450 Series Thermal Mass Flowmeter by COMATE is designed for air and nitrogen applications. It features a compact design with a smaller enclosure and thinner insertion tube probe, suitable for pipes ranging from DN25 to DN500. It can be installed or removed without stopping the fluid flow, making it cost-effective for compressed air and nitrogen applications. The flowmeter operates on thermal diffusion theory using two RTDs to measure gas flow velocity and temperature changes.

Applications
The flowmeter is ideal for applications involving air and nitrogen, such as compressed air, venting air, aeration, process protection nitrogen, and combustion air.

Product Features
  • 100:1 turn down ratio across five ranges.
  • Large LCD screen with dual-line display and three setting buttons.
  • Low-cost economical model with optional online data logger.
  • No pressure loss, suitable for any pipe shape with known sectional area.
  • High accuracy data acquisition circuit ensuring repeatability and accuracy.
  • Electrical structure with total isolation for excellent EMC properties.
  • Wide voltage range input (15V~32V) and self-protection design.
  • Self-diagnose function for easier troubleshooting.

Process Connection
The TGF450 Series offers two installation types: insertion and in-line. The insertion type allows for online installation and maintenance, while the in-line type is delivered with a pipe matching the field pipe's inner diameter. Both types are made from stainless steel, with options for different materials upon request.

Special Designs
  • Anti-ejection design for high-pressure applications.
  • Ball valve mounting for easy removal without stopping flow.
  • Hot taping driller for installation without stopping flow.
  • Online data logger and monitoring system for remote data access and reporting.
  • Bluetooth communication and COMATE app for smartphone access.

Packing
The flowmeter is packaged in a paper carton with installation accessories, a manual, and a calibration certificate. Each unit is calibrated on a sonic nozzle calibration system for accuracy and durability.

Specifications
  • Media Compatibility: Air, Nitrogen, Oxygen.
  • Pipe Diameter: DN25~400mm for insertion, DN15~300mm for in-line.
  • Flow Velocity Range: 0.3~150 Nm/s.
  • Accuracy: 1.5% RD + ±0.5% FS.
  • Temperature Range: -40~+150°C.

TGF450 Series Thermal Mass Flowmeter-1

Comate Intelligent Sensor Thermal mass flow meter datesheet TGF450 Series Thermal Mass Flowmeter 1. Brief Introduction TGF450 Series Thermal Mass Flowmeter is COMATE’s latest technology specially designed for air and N2 applications. It has more compact design, which means smaller enclosure and thinner insertion tube probe. Due to its small diameter insertion probe and shorter high-sensitive sensor, it can be used on pipes from DN25~DN500. In some higher pressure applications, it can be installed / removed without stopping the fluid, as the pipe is thinner, field engineers will be able to insert the meter to pipe very easily. Also, to fulfill the cost-saving demand in compressed air and N2 applications, TGF450 will be the most cost-effect model in the market. TGF450 Series Thermal Mass Flowmeter measures the gas mass flow base on thermal diffusion theory. It has two RTDs as its sensors, one of which sense the velocity of the gas flow (RH) and the other one will detect the temperature shift of the gas flow (RMG) . When the two RTD are in the gas flow ,the RH will be heated while the RMG will sense the temperature changing of the gas flow. More heat will be taken away as the velocity of the gas flow increasing ,so the temperature on RH will decline According to King’s law, the heating power P, the temperature difference ΔT (TRH-TRMG) and the mass flow rate are mathematical related . P/△T=K1+K2 f(Q)K3 , the K1、K2、K3 are constants related to the properties of the gas. TGF Series Thermal mass flow meter is designed base on constant power measuring method, thus the RTD is heated in a consistent power and will be more durable and stable. That is why TGF flow meter has less problem of zero-off which may caused by a function failure of RTD due to over-heated in long term. Email: info@comateflowm

Comate Intelligent Sensor Thermal mass flow meter datesheet 4. Process connection The TGF450 Series Thermal Flow meter has two different installation types, one is insertion and the other is in-line type. The insertion type can be installed and maintained on line. To install it, you have to weld and install a socket with screw thread outside on the pipe and install a 1 inch or 1/2 inch ball valve on the base. Then drill a hole of 13mm (or 22mm) diameter on the pipe with a special tool and install the flow meter on the pipe through the hole. The position and depth of how the sensor is fixed have...
