Hot wire anemometers based on h fv 4. 11 Introduction to flow meter reference design Flow meter based on MC9S08GW64 is a low-cost low-power system. In its simplest form the device consists of a short converging section leading to a throat and followed by a diverging section.

For 585 Main Steam Line use Liquid a nd Steam Horizontal orientation for mounting recommendations. Turbine flow meters where frequency velocity 6. Low-power low-cost able to run on battery and with automated meter reading AMR.

The key uses of these meters are presented along with their advantagesdisadvantages and system considerations. An annubar is another type of meter that can be inserted into a pipeline for accurate measurement of the flow rate. Flow measurement system including primary flow device utilized to measure wastewater flow conforms to recognized design and installation standards and any deviation from standard conditions be will documented.

This is also the reason that the next flow meter type was developed. Inferential type flow meters. It still does have a certain amount of pressure drop but it is significantly less than the orifice type meter.

Variable area flowmeters can be used in laboratory and industrial applications and when compared with other types of flow instrumentation are the most economical for indicating flow rate measurement when taking into account practicality and accuracy. Types of Flow Meters. The venturi flow meters can be stored indefinitely indoors in a clean non-corrosive environment.

Of the system operations. Clean or dirty Wet or dry Hazardouscorrosive or safe Single or multi phase Laminar of turbulent Varying pressure Contents provided in this presentation are for reference purpose the detailed theory to be readwritten from respective text bookClass Notes Varying pressure Varying temperature. As a result there are different types of flow measuring techniques that are used in industries.

Flow measurement pdf 1. Meters should be stored away from high traffic areas in order to minimize damage risk. A Venturimeter is a device meant for measuring the quantity of a liquid flowing through a pipe.

Meters must not be stacked. To determine flow simply read thegraduated markings at the center of the float. Turbine flow meter installation.

The design of the annubar allows it to be easily inserted into the flow stream when needed. 1 The flowmeter orientation recommendations may vary for the Gear-Drive Flo-Tap Annubar Type. Differential-pressure electromagnetic magmeter Coriolis and ultrasonic the last of which includes Doppler-shift and transit-time flow meters.

This design fulfils the basic market requirement for the Flow meter. A Obstruction type differential pressure or variable area b Inferential turbine type c. The vane air flow meter and Karmen vortex are two older styles of air flow sensors and they can be identified by their shape.

Building High Quality Flow Products Since 1946. The meter works by measuring the difference between the total fluid pressure and the static pressure over a large cross-sectional area of the pipeline. Pressure drop devices based on Bernoulli Principle a Venturi b Orifice plate c Pitot tube 2.
