Multivariable Vortex Flowmeter

Vortex flowmeter is based on Carmen (Karman) vortex principle study of production, mainly used for industrial pipe flow measurement fluid medium, such as a gas, liquid, vapor and other media. It features a small pressure loss, large range, high accuracy when measuring actual volume flow is hardly affected by fluid density, pressure, temperature, viscosity and other parameters. No moving mechanical parts, so high reliability and low maintenance. Instrument parameters can be long-term stability. Vortex flowmeter piezoelectric stress sensors, high reliability, can work in the operating temperature range of -20 ℃ ~ + 250 ℃ for. Analog standard signals, digital pulse signal output, easy and supporting the use of computers and other digital systems, is a more advanced and ideal measuring instruments.

Energy measuring.
Energy into primary energy (coal, crude oil, coal bed methane, LPG and natural gas), secondary energy (electricity, coke, artificial gas, refined oil products, liquefied petroleum gas, steam) and energy carriers working fluid (air, oxygen, nitrogen, hydrogen, water). Energy measurement is scientific management of energy, to achieve energy saving and improve an important means of economic efficiency. Flow Meter is an important part of energy measurement instruments, water, artificial gas, natural gas, steam and oil these common energy use of the extremely large number of flow meters, energy management and they are an indispensable tool for economic accounting.

what's advantages of Wet gas flow measurement ?

Wet gas meter

what's the features of marine fuel flow meter ?
In accordance with the requirements of marine diesel flow meter is properly installed, you can guarantee with sufficient precision, accuracy is usually cumulative value of up to 0.5, more 0.2, and is a more accurate flow measurement instruments. However, if the flow rate of the measured medium used.

Small, the impact of leakage error of the instrument will be highlighted and can no longer ensure sufficient accuracy. Therefore, different types and specifications of the diesel flow meter for use with a minimum allowable value, only when the actual measured flow rate is greater than the lower limit flow allowed value, the measurement accuracy can be guaranteed. Heavy meter measured media to pay attention to the temperature not too high, it will not only increase the measurement error, but also the gear stuck may occur. To this end, heavy oil flow meter in the instrument specified temperature range.

Attentions of Boat Fuel Meter.
Marine diesel meter pipeline should be clean before installation. If the liquid contains solid particles, the filter must be installed upstream pipeline; heavy oil flow meter straight pipe before and after no certain requirements. It can be mounted horizontally or vertically. When installed, it should be oval gear flow meter and the rotation axis parallel to the ground

Flow measurement independent of the state of a fluid flow, because oval gear flow meter is to rely on the indenter measured medium oval gear driven rotating metering of.

The greater the viscosity of the medium, from gear and metering space leaked gap smaller amount of leakage, so sticky skin greater nuclear test medium, the smaller the leakage error, to measure more favorable.

Marine diesel meter high measurement accuracy, but not for a fluid containing solid particles (solid particles will gear stuck, so that the flow can not be measured). If the measured liquid medium mixed with gas, can cause measurement errors.

how to work of thermal mass flow meter ?

What's the principle of thermal mass flowmeter?

To measure gas flow by measuring the cooling effect of the heating element within the gas flowing through the meter when the. There are within the measurement section of gas through two resistance elements, one of them as the temperature detector, and the other as a heater. A temperature sensing element for detecting the temperature of the gas, varying the current through the heater to maintain a constant temperature difference between the temperature and the measured temperature of the gas. When the gas flow rate increases, the greater the cooling effect, so that a constant temperature shall be kept between RTD current is greater. This heat transfer is proportional to the gas mass flow rate, i.e., current is supplied to the gas mass flow rate has a corresponding function to reflect the flow of gas.

what's the advantages of thermal mass flow meter ?

Thermal mass flowmeter to measure the flow rate (gas 0.02 ~ 2m / s) micro flow; submerged thermal mass flowmeters measure the flow rate of low to medium high (gas 2 ~ 60m / s), plug-in thermal mass flow count more suitable for large diameter. [1] 
Thermal mass flowmeter has no moving parts, no shunt heat distributed unimpeded flow meter parts, the pressure loss is very small; hot distributed instruments and immersion of the instrument with a shunt, although in the measurement pipe in the home have Baffles, but the pressure loss is not great.
Thermal mass flow meter performance is relatively reliable. Compared with the derivation of mass flow meters, without temperature sensors, pressure sensors and computing units, etc., only the flow sensor, composed of simple, small probability of failure occurs.
Instrumentation, heat distributed instrumentation proved for H2, N2, O2, CO, NO and so close to the ideal gas of diatomic gas, do not use these special calibration gas, calibration directly on the air for only about 2% difference; for Ar , He and other single-atom gas is then multiplied by the factor 1.4; for other gases in terms of the specific heat capacity is available, but may be slightly larger deviation.
Specific heat capacity of the gas will change with pressure and temperature, but the temperature and pressure used in the vicinity of small changes can be regarded as a constant.

the flow meter which used to measure lubricating oil

Lubricating oil flow meter 

Mainly dedicated lubricants meter oval gear flow meter to measure, for precise measurement of continuous or intermittent flow or transient pipe flow liquid. It is particularly suitable for flow measurement of heavy oil, polyvinyl alcohol, resins and other high viscosity media.

Flow measurement independent of the flow state of the fluid, which is due to oval gear flow meter is to rely on the indenter measured medium oval gear driven metering of rotation.
The greater the viscosity of the medium, from gear and metering space gap smaller amount leaked leak, so sticky skin greater nuclear test medium, the smaller the leakage error, to measure more favorable.
High precision measurement of oval gear flow meter is suitable for measuring high viscosity medium traffic. 
Users should match it with strainer if there is solid particles in fluid. and 
but not for fluid containing solid particles (solid particles will gear stuck, making it impossible to measure the flow).
 If the measured liquid medium which is mixed with gas,then you user should venting device.
