LEOMI is a 9001:2015 company that ensures that products and services meet customer needs through an effective quality management system.   LEOMI thermal mass (calorimetric ) flow meters work on the physical principle of thermal dispersion from a heated element to an ambient medium (such as air or gases). It is affected by velocity, density (temperature and pressure), and the characteristic of the medium. T...

Gas flow meters are instruments that measure the flow rate of a liquid or gas, whether linear, nonlinear, mass, or volumetric. This is very useful for machinery that uses gas or liquid as part of its operation. Having a small flow rate means the machine probably won't work, and exceeding the recommended flow rate can be disastrous. A gas flow meter can be used to measure the current flow rate within a machine; however, before buying a gas flow meter, it is recommended to find out what type of fluid is being measured and other questions. It's also helpful to compare two or more gas flow meters to find the best one for the job. This article will explain what a gas flow meter is, what it does, and how to find the best one for the application you want to use. A gas flow meter can be used for any machine that uses any type of fluid in its standard operation. It can measure the flow rate of a fluid in one of four different ways: linear, nonlinear, mass, or volumetric. A gas flow m...

  The efficient operation of today’s power plant depends largely upon accurate & repeatable measurement of primary and secondary airflow to coal mills, flue gas recirculation flow, overfire airflow, airflow to individual burners, etc. Flue gas or Stack gas emission flow rate measurement is nowadays important for quantifying emission (CEMS) for environmental reporting for Govt. Authorities for pollution control. Flue gases are gases emitted due to the combustion process due to heating of fuel (liquid or solid or gaseous) & Air with a stoichiometric ratio in: Boiler Heating Process furnaces FLUE GAS PRODUCTION DUE TO COMBUSTION MAINLY CONSIST OF  : Nitrogen (N2)  Carbon monoxide (CO)  Carbon dioxide (CO2) Traces of Sulphur dioxide (SO2),  Nitrogen oxides (NO, NO2)  Particulate matters (SPM)  Moisture Flue Gases are gases emitted due to combustion process due to heating of fuel (liquid or solid or gaseous) & Air in: Thermal Power Plant  S...

Are you able to find a reliable manufacturer of Insertion Thermal Mass flow meter with an In-house calibration facility in INDIA? Facing problem in validating/calibration of your existing Insertion Thermal Mass flow meter, or Air velocity Instruments? THEN, THIS ARTICLE IS FOR YOU. LEOMI has developed ways to optimize your existing air & gas flow measurement systems. LEOMI has newly commissioned India’s first in-house latest State-of-the-art Wind Tunnel, Made in Germany for Air Velocity Calibration and anemometer calibration services. It is certified as per ISO-17025 and DAkkS Germany traceability for air flow velocity ranges from 0.2 m/s to 75 m/s with flow uniformity of ±0.2%. The wind tunnel is constructed according to the Göttinger-type is a Closed designed circular tunnel with 180mm Nozzle diameter with 320mm open working section. Göttinger-type may be operated optionally using a closed section of measurements. The design requires low blower power and silence than other Eiffel...

  This article talks about the basics of flow profiles, installation criteria, end-user application considerations, and how to use flow conditioning to improve flowmeter's accuracy in areas where a sufficient flow profile isn't possible. Number- 1: Understanding velocity profile Inside a pipe, fluids, such as gas, flow at different speeds. When gas flows through a circular pipe, particles in contact with the surface of the pipe wall come to a halt (W0), forming a boundary layer. To maintain the mass flow rate through the pipe, the gas velocity in adjacent layers slows due to friction and the gas velocity in the midsection increases at the center is (Wmax). The velocity profile is the velocity distribution through the tubing. The fully developed velocity profile is almost parabolic, whereas the turbulent profile is almost flat. It is possible to determine velocity anywhere within the pattern by understanding the velocity profile. Number- 2: ‘Installation location is critical’ Th...

Thermal mass flow technology is evolving and removing some of the challenges faced e two design working principles:     Constant Temperature Anemometry   The constant-temperature sensor design maintains a constant temperature differential between a heated sensor and a reference sensor; the amount of power required to maintain the differential is measured as an indication of the mass flow rate. Constant-temperature thermal mass flowmeter currently popular with features as below: Active  High-frequency response  The low electronic noise level Immunity from sensor burnout when airflow suddenly drops  High rangeability Compatible with various RTD Pt-100 sensors, such as hot thin film, wire wound, etc.  Applicability to gas flows     Constant Power Anemometry   Constant power sensor design maintains constant power between two temperature sensors which will provide a flow rate proportional to the temperature of the gas flows. This design is le...
