Variable Area Metal Tube Float Flowmeter Gas Level Small Flow Pointer DN15-DN100

Description
When the fluid filling the pipe flows through the throttling device in the pipe, the flow stream will form a local contraction at the throttling piece of the throttling device, thereby increasing the flow rate and lowering the static pressure, thus creating pressure before and after the throttling piece. Drop, that is, pressure difference. The greater the flow rate of the medium, the greater the pressure difference generated before and after the throttling member. Therefore, the fluid flow rate can be measured by measuring the pressure difference. This measurement method is based on the law of conservation and the law of flow continuity.
The intelligent throttling device (orifice flowmeter) is a new generation flowmeter that integrates flow, temperature, and pressure detection functions and can automatically compensate for temperature and pressure. It adopts microcomputer technology and new
micropower consumption technology and has powerful functions. , compact structure, simple operation and easy to use.

use
LG/FB type standard annular chamber orifice plate and flange orifice plate throttling device is a scaleless flow measurement device. It is used in conjunction with pneumatic or electric differential pressure transmitters or double bellows differential pressure transmitters. In metallurgy, chemical, petroleum, and electric power industrial systems, the pressure difference generated by liquid, gas, and steam flowing through the orifice plate with a medium temperature of ≤ 400 ℃ is continuously measured. The transmitter converts the pressure difference signal into a proportional output signal, and then There are secondary instruments or regulators that record, indicate or regulate the measured flow.

Fundamental
Install throttling parts such as orifice plates or nozzles inside the pipeline. Since the aperture of the throttling part is smaller than the inner diameter of the pipe, when the fluid flows through the throttling part, the flow beam cross section suddenly shrinks and the flow speed accelerates. The static pressure of the fluid at the rear end of the throttling member decreases, resulting in a static pressure difference before and after the throttling member (see Figure 1). There is a definite numerical relationship between this static pressure difference and the flow rate of the fluid, consistent with Q=K . Root sign △ P . Use a differential pressure transmitter (or differential pressure meter) to measure the differential pressure before and after the throttling member to measure the flow rate.

Installation requirements
The installation of the throttling device is related to the following pipe sections and pipe fittings: resistance piece No. 1 and resistance piece No. 2 on the upstream side of the throttling piece, resistance piece No. 1 on the right side under the throttling piece, resistance piece No. 2 upstream of the throttling piece to The pipe section between the downstream No. 1 resistance piece and the differential pressure signal pipeline, etc.

Specification
LF-A series integrated orifice flowmeter is a split-flow flowmeter with floating
The sub-flow meter is installed next to the measuring pipe and is integrated with the orifice plate for flow splitting.
It has four different connectors for users to choose from, namely "threaded" (AT),
"Flange" (AF), and "Clamp" (AC), separate type (AD). Fluid flows through the main
When the orifice plate is installed, a differential pressure is generated on the front and rear sides of the orifice plate. This differential pressure value is related to the flow value.
Equivalently, a float flowmeter is installed in the branch inlet and outlet, so that the flow through the float
The flow rate of the meter is equivalent to the flow rate through the main pipe, so the fluid passing through the main pipe
The flow rate can be indicated by the scale of the glass float flowmeter.
·Medium temperature: PVC: 0~60℃,
SS304:0~120℃
·Accuracy: ±2.5%
·Working pressure: 1.0MPa

Installation direction:
The installation direction of the LF-A orifice flowmeter can be changed as shown in the figure on the right. The flow direction is: bottom → top,
Left→right, right→left and top→bottom, it is very easy to change the flow direction of the flowmeter in the field.
