Overview

1、 The R108 thermal gas mass flowmeter has two types: insertion type and measurement tube type. The insertion type sensor has a diameter of 1/2 and a probe length of up to 36 (914mm) (longer sensors can also be manufactured); The measuring tube sensor has a measurement range of 1/4 to 6 (6.25mm to 152mm) ..

Product Details

1、 Principle

The 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.

5、 Product composition

The thermal gas mass flowmeter consists of an integrated flow converter and a flow sensor. According to the type of flow sensor, it can be divided into plug-in and pipe section thermal gas mass flow meters.

Pipe section thermal gas mass flowmeter: It is equipped with a process pipeline with the same inner diameter as the on-site pipeline at the factory. The connection method with the on-site pipeline is flange connection or threaded connection, and the flange standard complies with the national standard GB/T9119-2000.
The pipe segment sensor is suitable for pipeline diameters ranging from DN15 to 2000mm. The sensor material is stainless steel, and the pipeline material is carbon steel or stainless steel. Special materials should be specified when ordering. (as shown in the table below)

pipe diameter	Scfm	Nm3/h
3"（80mm）	0-1600	0-2720
6"（150mm）	0-6400	0-10870
8"（200mm）	0-11100	0-18860
10"（250mm）	0-18200	0-30920
12"（300mm）	0-24900	0-42300
16"（400mm）	0-43350	0-73700
20"（500mm）	0-67700	0-115150

Note: To determine if the plug-in flow rate meets the requirements, divide the maximum flow rate by the cross-sectional area of the pipeline to see if the flow rate is within the specified range.
