Orifice plate meter installation

Orifice plate flow meter works together with an orifice plate, differential pressure transmitter , with Differential Pressure Measurement principle.

Easy installation. Orifice plate flow meters can be used with gases, liquids, corrosive, and high temperature fluids. Orifice flow meters can measure steam, gas, liquids, and many industrial areas. Applications include steam flow, boiler feedwater, and fluid flow rates in building water lines.

Sino-Inst, Manufacturer for differential pressure flow meters. Including the Orifice plate, Venturi, Annubar, etc. Suitable for liquid, gas, and steam flow measurement. Please contact our sales engineers for technical support! SI-LG integrated orifice flowmeter is a high-range ratio differential pressure flow device.

Composed of standard orifice plate and multi-parameter differential pressure transmitter or differential pressure transmitter , temperature transmitter and pressure transmitter.

It can measure the flow of gas, steam, liquid and natural gas, and is widely used in process control and measurement in petroleum, chemical, metallurgy, electric power, heating, water supply, and other fields.

For the common square edge concentric bore orifice, the bore and bevel is the standard method of limiting the plate edge thickness. Unless otherwise specified, plates will be beveled to the currently accepted standards.

The quadrant edge bore is an orifice with the inlet edge rounded. Instead of beveling, the plate is counterbored to the desired edge thickness. Thickness at the throat is equal to the radius. This bore is specifically designed for viscous fluids such as heavy crudes, syrups, and slurries with Reynolds Numbers below , Eccentrically bored orifice plates are plates, with the orifice off-center, or eccentric, as opposed to concentric.

Eccentric orifice plates are used in many industries, including heavy and light chemicals, steel, paper, nuclear and petrochemicals. Segmentally bored orifice plates are provided for measurement, where solids are entrained in a gas or liquid flow stream. The segmental opening may be placed either at the top or bottom of the pipe. Industries using these bores include sewage treatment, steel, chemical, water conditioning, paper, and petrochemical.

The RTJ type orifice plate incorporates an integral gasket, either oval or octagonal ring, for mounting between ring type joint flanges. It is based on proven technology, has no moving parts and is suitable for high temperature and pressure applications.

Plate thicknesses depend on line size and differential pressure and should be sufficient, to prevent the plate from bending under operating conditions. Orifice plates can be made in accordance with customer drawings as required. If you still have questions about orifice plate flow meters, Just contact us. Stainless steel pipes are strictly prohibited from being cut and opened by electricity or gas welding. Plasma or mechanical cutting or opening should be used.

Instrument threading pipes, cabinets, discs, etc. Insulated instrumentation lines below The aluminum alloy bridge should be short-circuited across the short-circuit.

The galvanized bridge should be tightened with not less than two anti-loose screws. The length should be reliably grounded within 30 meters. If it exceeds 30 meters, a grounding point should be added every 30 meters. When the instrument line or instrument line of different grounding systems shares a slot with the power line, they are separated by a metal partition.

It is strictly forbidden to use the gas welding method in the installation and processing of the instrument panel, cabinet, box and table. The welding method should not be used for the installation and fixing.

The mechanical opening method should be adopted for the opening. The blind end of the instrument for heating and returning water should not exceed mm.

The lower part of the transmitter drain valve should be equipped with a cap that prevents leakage of the valve especially in the explosion-proof area. The orifice flow meter and its threading pipe and pressure pipe are fixed at one end in a thermal expansion zone such as a tower, an accessory that moves with the thermal expansion of the tower , and one end is fixed in a non-thermal expansion zone such as a labor protection room , and the instrument should be connected according to On the actual situation of the site, the flexible pipe, the threading pipe and the pressure pipe must have a certain thermal expansion margin.

The tower bridge and the threading pipe shall be provided with thermal expansion joints or flexible joints according to the actual conditions on site.

Orifice flowmeter installation guidelines The orifice flowmeter is a high-range differential pressure flow device,that combines a standard orifice plate with a multi-parameter differential pressure transmitter or differential pressure transmission, temperature transmitter and pressure transmitter to measure gas and steam , liquid and natural gas flow.

Common orifice flowmeter installation error 1. Straight pipe sections before and after the orifice plate do not meet the requirements The function of the straight pipe section before and after the orifice plate is to ensure the stability of the fluid flow in the pipe.

Reverse the reverse side of the hole Before installation, the flow direction of the medium in the pipeline and the direction of the orifice plate should be correctly identified, otherwise the measured value will be low.

Orifice Plate Installation Detail.

How does Orifice Plate Work? General Installation requirements: The orifice meter must be installed between two mating flanges in the pipe. For liquid metering, the pipe should run full at the measuring section.

The diameter of the tube must be circular over the measured length. The internal surface of the measuring pipe must be clean and free of scale, pitting and deposits or any other possible source of turbulence.

The pipe and pipe flanges should be lagged for orifice plate steam applications. Flanges, collars, wide-open gates, reducers or bends, elbows or tees which are all in the same plane — 10 pipe diameters Angle turns in two planes — 50 pipe diameters Pressure regulator, control valve or similar apparatus or fitting — 75 pipe diameters.

A Horizontal Installation for Clean Fluids With an horizontal line, the pressure connections should be made at the SIDE of the line to allow trapped vapors to escape from the connection lines, and to prevent sediment from entering in these lines. Position of Pressure Tappings for Liquid Measurement. Horizontal Installation for Clean Fluids.

Horizontal Installation for dirty or corrosive Fluids using a seal. Horizontal Installation for clean noncondensable gas. Position of Pressure Tappings for Steam Applications. Horizontal Installation for vapor or dirty or consensable gases. Depending on the orifice plate installation direction the impulse piping should be set up as shown below : In the case of having an ascending fluid, the impulse piping must be configured as shown below. Orifice plate flange taps orientation fluid going down.

Vertical installation for clean liquids. Vertical installation for dirty or corrosive liquids. Vertical installation for clean noncondesable gases. Vertical installation for vapor condensable gases or dirty gases. How to convert actual flow to normal flow?
