1、 Overview

The DT-R108 thermal gas mass flowmeter comes in two types: plug-in and tube type. The plug-in sensor has a probe with a diameter of 1/2 "and a maximum length of 36" (914mm) (longer sensors can also be manufactured); There are measuring tubes with measuring tube sensors ranging from 1/4 to 6 "(6.25mm to 152mm), equipped with built-in flow regulators to eliminate the need for long straight pipe sections upstream and downstream. The pipeline connection can be flange, NPT thread, or welded. The material is 316 stainless steel, Hastelloy C alloy or other materials.

2、 Application

1. Measurement of oxygen, nitrogen, hydrogen, chlorine, and multi-component gases. (excluding acetylene gas).

2. Measurement of blast furnace gas and coke oven gas.

3. Measurement of flue gas.

4. Aeration and chlorine gas measurement in biogas and water treatment.

5. Compressed air measurement.

6. Measurement of gas flow rates such as natural gas, liquefied gas, and flare gas.

7. Measurement of primary and secondary air flow in power plant blast furnaces.

8. Measurement of flow rate in underground ventilation or exhaust systems.

3、 Characteristics

1. Measure gas mass flow rate without temperature or pressure compensation.

2. Large range ratio, measuring flow velocity range: 0.1Nm/s to 100Nm/s.

3. No pressure loss, suitable for any shape of pipeline with known cross-sectional area.

4. Corrosion resistant sensor, suitable for measuring corrosive gases.

5. The expert algorithm for the full range range is particularly suitable for large-diameter measurements, ensuring measurement accuracy and suitable for trade settlement.

6. Can perform excellent leak detection and equipment work on process pipelines.

7. The construction volume is extremely small, and due to the use of an insertable structure, it can be installed and maintained online.

8. Base type instruments can display on-site and have alarm control.
