Tenda LGB throttle device

An overview of the standard orifice plate throttling device structure is the simplest, most adaptable product. Standard orifice plate flow measurement is a differential pressure generating means, with a variety of differential pressure gauge or differential pressure transmitter measures the flow pipe of various fluids. It is a set of standard orifice flow, temperature, pressure detection functions, and can be temperature, pressure automatic compensation of a new generation of flow meters, the standard orifice plate uses advanced computer technology and micro-power technology, powerful, compact , simple, easy to use. LGB-type standards orifice design, manufacture and use comply with the requirements of international standards ls05167 or national standards GB / T2624's. Standard orifice plate features: You can measure a variety of gases, liquids, steam flow. Adapt to a wide range. Simple structure, strong, easy to install, reliable, stable performance. It does not require actual flow calibration. Moderate accuracy. It can be used with smart differential pressure transmitter, to achieve temperature and pressure compensation or fieldbus communication. Standard orifice of the main technical parameters:? Pressure way: fillet (donut or a separate drilling), flange pressure, the span to take pressure. ? Nominal (MPa): ≤40 (≥ followed by high pressure lens orifice or all-welded) Nominal Diameter (mm):? DN50 ~ 1000 (standard plates) or DN <50 (Integral Orifice), DN > 1000 (flat plate) Accuracy (uncertainty):? ± 0 5% - ± 1 5% II. Features ▲ throttling device structure is easy to copy, simple, solid, reliable performance, long life, low price . ▲ plates calculated using international standards and processing ▲ wide range of applications, all single-phase flow Jieke measure, part of the mixed phase flow can also be applied. ▲ standard throttling device without actual flow calibration can be put into use. ▲ a body orifice installation easier without joining pipe, can be directly connected to the differential pressure and pressure transmitters. Smart Features ▲ using monocrystalline intelligent pressure sensor ▲ precision, improve self-diagnostic function ▲ Intelligent orifice flowmeter its range of self-programmable adjustment. ▲ can display the cumulative flow, instantaneous flow rate, pressure and temperature. ▲ with online dynamic full compensation function, but also has a self-diagnosis, self-set range. ▲ with a wide variety of communication interfaces ▲ ▲ high stability measuring range, greater than 10: 1 smart technical indicators ▲ precision: ± 0.075% ▲ high stability: better than 0.1% FS / Year ▲ High Static Pressure: 40MPa ▲ 5 years of continuous work without adjustment ▲ negligible temperature, static pressure ▲ resistance to high overvoltage III Selection Model Description LG throttling device, code-named its structure features two basic categories K orifice nozzles, etc. Code Nominal P (105Pa) 2.5 2.5 10 10 16 16 25 25 64 64 100 100 200 200 Code Diameter (mm) 10 ~ 1600 10 ~ 1600mm Code subdivided according to their structure in the form of H standard orifice (Central Office) Y standard orifice plate (flange ) K standard orifice (drilling) I ISA 1932 nozzle diameter nozzle L W G Venturi nozzle Venturi tube S classic double round orifice plate Z Q conical entrance orifice R 1/4 hole plate P eccentric N whole plate (built) wedge plates T plate X not in the list of special throttling device codenamed medium liquid gas vapors 4 3 Symbol compensation in the form of high temperature liquid N without pressure, temperature compensated pressure-compensated output P T with a temperature compensated output Q with pressure, temperature compensated output code transmitter differential pressure measuring range 0 1 Low Range Differential Pressure Differential Pressure Range 2 Range 3 high differential pressure range code if throttling device with live display W sensor X smart throttle (meter) Code external 24VDC power supply mode 0 1 3.6V battery powered
