FLOWCAL TECHNICAL SERVICES PRIVATE LIMITED is a professional organization engaged in the marketing and after sales service support of Analytical Instrumentation products for Steel plants, Foundries, Cement plants Mechanical and Automobile engineering Industries, Space Research and Atomic Energy Research, Biomedical, Power production & Transmission, Semiconductor and other Research Institutions. We at NIS have highly experienced and dedicated Instrumentation Professionals for marketing and providing effective after sales service support for our customers. Our engineers have been trained at the manufacturers’ plants and are highly motivated to provide excellent support for solving complex problems that arise in the critical applications involving on line instruments processes.
The flowcal flow meters are chosen because of the reliable, traceable measurement results. Reliable measurement data is key to making the right decisions. Since sensors and electronics may drift, might get polluted or mechanically wear out, it is important to maintain and calibrate your meters using a reliable, traceable reference standard.
OUR PRODUCTSWith all flowcal service programs you will have guaranteed reliable results. With each service you will have a flow meter that is: Inspected Cleaned Repaired Re-calibrated Features the latest firmware
OUR SERVICESLiquid flow meter calibration can be done in several ways, but always involves comparison and adjustment of the flow meter under test to conform to a standard. Some of the most widely-used flow meter calibration procedures are:
Master meter calibration compares the measurements of a flow meter under test to that of a calibrated flow meter or ‘master’ flow meter operating at the desired flow standard and adjusts its calibration accordingly. The master flow meter is usually a device whose calibration is set to a national or international standard.
To perform Master meter calibration:
Gravimetric calibration is one of the most accurate and cost-effective volumetric and mass flow meter calibration procedures. The gravimetric method is ideal for liquid flowmeter calibration in oil, water purification, and petrochemical industries.
TTo perform a gravimetric calibration:
In the piston prover flow meter calibration procedure, a known volume of fluid is forced through a flow meter under test. The piston prover is a cylindrical device with a known internal diameter. The piston prover contains a piston which produces volumetric flow by positive displacement. The piston prover method is ideal for ultrasonic flow meter calibration, fuel flow meter calibration, and turbine flow meter calibration to a high degree of accuracy
To perform a piston prover calibration:
Flow meter calibration is the process of comparing the pre-set scale or metering of a flow meter to a standard scale of measurement and adjusting its metering to conform to the standard. Calibration is an essential aspect of instrumentation in a broad range of industries that require high-accuracy measurements with a negligible percentage of error e.g. in Oil & Gas, Petrochemical, and manufacturing. Flow meters are calibrated by comparing and adjusting their metering to correspond with a predefined standard. Flow meter manufacturers typically calibrate their products in-house after production or send them to an independent calibration facility for adjustment. .
Flow meter calibration involves comparing the measurements of a flow meter in operation to that of a standard flow measurement device under the same conditions and adjusting the scale of the flow meter to be in close agreement with the standard. Flow meter recalibration involves calibration of a flow meter which is already in use. Periodic recalibration is essential as flow meter readings will often go ‘out of phase’ over time due to variable conditions involved in industrial processes. The main difference between the two procedures is that flow calibration is done before the meter is sent out for use while recalibration is done after the flow meter has been in operation for a while. Software tools can also be used to verify the accuracy of measurements after a flow meter has been calibrated.
