LGBH integrated orifice flowmeter

The orifice plate throttling device is perfectly combined with a differential pressure transmitter through a three valve group to form an integrated orifice plate flowmeter.

Integrated orifice flowmeter can be widely used in industries such as petroleum, chemical, natural gas, metallurgy, power, and pharmaceuticals for continuous measurement of volume flow or mass flow of various liquids, gases, natural gas, and steam.

2、 Characteristics:

a. Integrated structure, short and efficient pressure tube, no leakage points, easy installation

B. Compact structure, reducing signal transmission delay and corresponding fast speed

C. Balance the pressure without zero point error

D. The pipeline diameter has a wide range of applications, and the pipeline can reach 1200mm or larger

E. High measurement accuracy, wide range, and scalability

F. High temperature and high pressure resistance, suitable for various working conditions

G. On site digital display and signal remote transmission compatibility

3、 Flow meter type:

1. According to the measurement method, there are two types: volumetric flow rate type and mass flow rate type

2. Divided by installation and connection methods:
Quick installation: The pressure ring body of the orifice plate is clamped between the two flanges of the process pipeline.

Flange connection type: A pair of flanges of the flowmeter are connected to the flange of the process pipeline.

5、 Flow meter structure:
1. Basic structure

It consists of three main parts: orifice pressure sensing device, three valve group, and differential pressure transmitter.
2. Type of orifice plate

Standard orifice plate
3. Pressure collection method
Clamp on type: corner drilling for pressure measurement

• Flange type: pressure tapping on the flange
4. Three valve group and its function
Can make the integrated structure sturdy and reduce leakage points;
• Can confirm the zero point and correction of the transmitter online;
