Flow Meter Calibration Systemrecently supplied to a Customer in Kingdom of Saudi Arabia

3 or 4 Stainless Steel Tanks of Nominal Volumes from 150 Litresupto 12000 Litres are Mounted on Matching WeighingScales/Load Cells. Pressure Measurement devices are installedat both Upstream/Downstream of the test line to measure theInlet/Outlet Pressure of Water. Temperature Sensors withTransmitters are fitted in Each Collection/Weighing Tanks tomeasure the Temperature of Water collected.

Gravimetric Method : Better than 0.05%Comparison Method

The speciality of the system is itsthat enables Diversion of Flow into Collection Tanks or to

Water Reservoir per withoutdisturbing the Flow Rate. Precise Flow Control is achievedthrough employing VFD’s (Connected to Pumps/PLCs) &Electrically Operated Flow Control Valves. Very hugeUnderground Water Reservoir, with a capacity of

serves as uninterrupted Water source for performing flowCalibration thro’ recycling.

System’s Control Panel is designed in such a way to performmultiple tasks & to mount the Weighing Indicators & MultipleControl Switches/Knobs etc. Control Console is also equippedwith a Mounted PC with preloaded Software - to handle/operatethe process and Display the parameters like Flow Rate/TotalVolume, Temperature & Pressure readings. Control Console isequipped with precise PLC system to take care of the AutomationProcess of the System & is loaded with In-house designed “Flocal”Software which generates Calibration Report.

Process Flow Calibration System (FLOCAL)Larger Sizes

Gravimetric / Volumetric Method.

Nagman Instruments & Electronics Private Ltd. is an ISO 9001:2008Certified Company spread across PAN India, serving the global marketsince its inception in 1972 offering comprehensiveto customers through its various divisions viz. Domestic Marketing,Exports Marketing, Centre for Calibration and .

We are pleased to inform that has been formed as anunder NAGMAN Group of

Companies and is now registered as(NFLSS) incorporated on

14th March 2018 under Ministry of Corporate Affairs with RegistrationNo. AAM-2362.

Nagman have recently developed & introduced an Innovative/Hi-techto Calibrate Flow

Meters of (up to DN 300) with enhanced System Features& Facilities.

This Process Flow Meter Calibration System (Automatic / Semi-automatic / Manual) is designed for Calibrating the “Accuracy ofMeasurements” of varieties of Flow Meters (Coriolis Mass,Electromagnetic, Ultrasonic, Venturi, Orifice Plate, Turbine FlowMeters etc.) typically in sizes from DN 15 to DN 300 through

(Calibration thro’ ComparisonMethods also are achievable).

The System’s Pump House accommodates an array of pumps fromVery Low (1 m3/hr) to Very High (600 m3/hr x 2 Nos.) Flow Volume, withFrequency Converters (VFD’s) which control the complete watercirculation between the Storage Reservoir & Collection Tanks.

System’s Test Bed has Multiple (Three/Four) Test Lines toaccommodate/mount ‘Units Under Test’ (UUT). Each Test Line is fittedwith a Calibrated & Certified ‘Electromagnetic’ Flow Meter which servesas Flow Setting Device (Masters). One or more of Flow Meters (UUT’s)(Depending on the Sizes & Types of Flow Meters) can be Mounted &

Why CalibrateFLOW METERS

Flow Meter measures the rate of Flow of Fluid which

passes through it. Flow Meters are used in wide

variety of Applications where Accurate Flow

Measurements are critical in various Sectors like

Energy, Power, Refineries, Utilities, Water

Management, Aerospace, Pharmaceutical Industry

etc.

In Critical Applications like these,

Regular Calibrations assure you

that the Flow Meter’s Measurements are as accurate

as their specifications.

Even the most rugged Flow Meters can fall out of

Calibration with performance degradation over time -

even corrosion or dirt within the media that flows

through can shift the Accuracy of the Flow Meters.

it’s important to

Calibrate the Flow Meters to enable make reliable

Measurements.

It is every one’s responsibility to save water, which is a precious commodity.

After all, out of 100% of the Worlds’ Water resource, only 3% of the water is usable, this imposes moral

responsibility to precisely use this natural & scarce resource.

Nagman Designed & introduced ‘WATCAL’ – Water Meter Calibration Systems, for Calibrating the Accuracy of :

Domestic Water Meters, typically in sizes from

Industrial / Bulk Water Meters, typically in sizes from

and Bulk Water Meters are most commonly used in Housing and Industrial Sector

respectively, used to monitor & Control the non-revenue water. We provide Solutions for Accurate Metering,

Accounting & Recording Purpose.

Calibration routines can be performed in both Manual & Automatic mode - Nagman offers both (It is possible to

offer Semi-automatic mode also, kindly consult us)

The System can be designed to calibrate BTU Meters covering Heating / Cooling System for Hot / Cold Water Test.

Salient features and Essential modules of Nagman WATCAL - for various sizes of Water Meters, from DN 15 to 50

upto 300 are described in the following pages, making user Selection easier and simpler.

- DN 15 to DN 50

- DN 50 to DN 300

The “Flocal” Software will then generate Calibration Report.

Note :

Gravimetric Calibration can be performed up to 12,000 Liters volume on the basis of 1 minute (60 Seconds) campaign (i.e. Flow rate 12000 LPM).

For volume higher than 12,000 Liters (for e.g. flow rates higher than 12,000 liters / minute) Gravimetric Calibration Campaign time will be varied

according to the set flow rate.

** Volumetric Method :

Measuring Capacity By using One Diverter System & 2 Nos. of Large Volumetric Tanks (2000 - 3000 L) (Cascaded Double Decker).

Once Maximum Level (5000 L) reaches in Tank 1, the PROXIMITY SWITCH triggers the diverter system which diverts the flow into tank2 & Drains

the tank1.

When tank 2 reaches the Maximum level (5000 L), again the PROXIMITY SWITCH triggers the diverter system which diverts the flow into tank 1 &

Drains the tank 2.

And this process can go on till desired flow volume is Read (eg. 2 X 5000 L = 10000 L, 3 X 5000 L = 15000 L etc.).

(BELL PROVER METHOD)

Nagman is pioneer in manufacturing Gas Calibration System using Bell Prover method, as it is the most common method of calibrating

the domestic Gas meters used extensively for lower pressure calibrations.

In this device air is displaced into a calibrated bell, which raises or lowers as the bell is filled.Abath of oil or water acts as the seal.

The Test System with Bell Prover of Capacity (100L / 200L) will effectively cover Vey Low

Flow Rates. Accuracy: 0.5% F.S. It can test separately as per different gas meters. Bell Prover

has built-in Pump to deliver theAir at desired Pressure.

The ‘Calibration Standard’ of the Test system is “Bell Prover”,

Upto 4 / 8 Gas Meters (G 1.6)

which is considered a Primary (Calibration) Standard to Test &

Calibrate Domestic Gas Meters. The device is ideal for OEMs, Calibration Laboratories & Calibration Service Providers.
