Overview

The HC-HLV series plug-in delta flowmeter can be used to measure the flow rate of gases and liquids, with the following advantages: simple structure, easy installation and maintenance; Applicable diameter, wide range of applications; The power pressure loss of the pipeline is small, the pressure difference is large, and it can be measured in both directions; High precision, low requirements for straight pipe sections; High reliability, anti blocking, and can be used in quite harsh working conditions.

Product Details

The Delta flowmeter is a plug-in flow measuring instrument. Insert a delta bar sensor into the pipeline, and when fluid flows through the sensor, a high-pressure distribution area is generated in the upstream direction and a low-pressure distribution area is generated in the downstream direction.

It has the following characteristics:

1、 Widely used

HC-HLV seriesPlug in delta flowmeterIt is a high-performance flow sensor designed by using differential pressure working principle and online insertion installation method to accurately calculate and generate professional * through model data. It is a special throttling device whose output is differential pressure. The sensor measures pressure through a probe, which has two rows of unevenly distributed pressure holes in front and behind it. By averaging the different pressures or flow rates of the pipeline from top to bottom and from left to right through two rows of pressure holes, a differential pressure is formed, and then the mass flow rate or volume flow rate is calculated.

The material of the flow probe is 316L and it has multiple clock connections with the process pipeline; For media with high-density dust materials, online blowing devices can be used to ensure flexible use under various working conditions.

2、 Low power loss in pipelines

The pressure loss of a typical averaging tube flow sensor is much smaller than that of an orifice plate, only 5-10% of that of an orifice plate; On the other hand, due to the small pressure loss, there will be a small differential pressure (pressure difference between high and low pressure), which increases the requirements for selecting differential pressure transmitters and costs. Otherwise, the output accuracy of the transmitter will decrease because the range cannot reach full range. So a good probe must take into account both pressure loss and differential pressure. The special geometric design of the HC-HLV series Deltaba flow sensor fully considers this factor. The cross section itself is symmetrical, and the curved surface is divided into three parts. The facing part is a smooth section, allowing the probe to smoothly contact the medium; The second part is the acceleration section, which accelerates the flow velocity of the medium by an average of three times, and increases the pressure in the face section by increasing the contact surface with the medium; The third part is the peak of the high and low pressure boundary, where the resistance suddenly disappears and a low pressure zone is formed behind the probe. The actual color velocity spectrum can fully reflect the changes in the medium flow velocity. So, the design of the HC-HLV series Delta probe meets the requirements of low pressure loss and high differential pressure.

3、 High measurement accuracy

After third-party testing and according to the latest data, it has been shown that even in relatively short straight pipe sections, an accuracy of 1% can still be achieved. The straight pipe section with a precision of 1% is much shorter than ordinary products. The repeatability is 0.1%. Normal measurement accuracy; 0.2%. 0.5%, used for energy management accuracy; 0.1%, due to low pressure loss and minimal wear on the probe, as long as it is installed properly according to the calculation technology requirements, high accuracy can be maintained for a long time

4、 Low operating costs

Due to the small pressure loss, the power loss in the pipeline is also small. Generally speaking,HC-HLV seriesPlug in delta flowmeterThe operating cost is only one tenth of that of an orifice plate.
