ADDMAS Thermal Mass Flowmeters
Minimum Order Quantity: 1
1 Pack contains : 1 Unit
At Thermal Mass Flowmeter is one of the most advanced flowmeters in gas mass monitoring. The sensor of AT Thermal Mass Flowmeter is related to flow rate of the gas mass and meet the situation which the temperature and pressure are unstable Thermal sensor consists of two sensing elements - a velocity sensor and a temperature sensor that automatically corrects for changes in gas temperature.
Features:
Accuracy:
• AT series thermal mass flowmeter has well Repeatability, ± 0.1% of full scale. The accuracy of the system can reach ± 1 %. Although the accuracy of other kinds of flowmeter will be better than ± 1 %, the accuracy is hard to reach ± 1 % through the combination of temperature transmitter, pressure transmitter, secondary meter, the total error for the real system will be more than that value, especially when the component of flow changes. Because AT series thermal mass flowmeter directly measures mass flow, it has sensor and transmitter and display by its own. But the traditional gas flow meter needs to make up for a measurement system with temperature transmitter, pressure transmitter, secondary meter. According to reliable design theories, obviously, AT series thermal mass flowmeter possess a good reliabilities and measurement accuracies.
Wide Measuring Range:
• AT series thermal mass flowmeter use advanced intelligent chips and display alphanumeric 2 x 16 digit backlit LCD, it can display ten digits of cumulant flow and four digits of instantaneous flow and flow percentage and the self-check. There are three keys behind the display, which can switch display content and set various data. It also can use the remote-control which has three matching keys. You can do all operations by using the remote control with no cover opened. The unit of flow rate can set kg/h or Nm3/h. The connection has 4-20mA signal output and RS232 communicator, and adopting MODBUS or HART protocol.
Easy Installation:
• AT series thermal mass flowmeter can be installed on the level, uprightness and incline duct, but should be upright with a duct.
• AT series thermal mass flowmeter use flange hold way to install. It can provide a set of flange, bolt, and nut. series thermal mass flowmeter mate flange at random and used for welding on the trapping duct.
• AT series thermal mass flowmeter usually, need the 15D straight pipe. When the occasion cannot meet this requirement, you can choose our own rectifier.
