Liquid Flow Meter & BTU Meter Calibration


Flow Meter Calibration

The flow meter is calibrated by Calibrated Ultrasonic Flow meter. It has got two sensors which is mounted on pipeline at a specific distance and without disturbing the system flow is measured and compared with device under calibration.


BTU Meter Calibration

In this system, Flow & Temperature is measured by Calibrated instruments. These measured values are used to calculate Energy. This calculated value of Energy and reading of device under calibration is compared.

Covering calibration of temperature & humidity indicator with sensor, hygrometers, humidity sensors, data loggers, humidity chambers, environmental chambers, climatic chambers etc.



OVERVIEW

Absolute Pressure Calibration


We have acquired Absolute Pressure Calibration facility. We have Reference standard Druck – U.S.A. make that has accuracy of 0.05%.



OVERVIEW

Current Transformer Calibration


For calibration of Current Transformer , we have C.T. calibration Test Bridge, along with Burden Boxes, Current Source & Reference Current Transformers.

The Ratio Error and Phase Angle Error is calibrated against the Reference CTs of 0.1 class up to 1200 A.



OVERVIEW

Thermal Mapping, Temperature Uniformity Serve (TUS), System Accuracy Test (SAT)


Temperature Mapping / Validation / Temperature Uniformity Testing of furnace / ovens , cold chambers etc

This is done by locating various temperature sensors inside the equipment. These are connected to data logger. When actual temperature reaches to desired set temperature , it allows to stabilize & after thermal stabilization temperature readings are noted for 30- 40 minutes or as per requirement. These methods are based on various National & International standards.


System Accuracy Testing & Loop Testing

System Accuracy test is basically to verify the total measuring system. In this case dry block calibrator is used to simulate the furnace temperature. The furnace temperature sensor is inserted in the dry block calibrator along with our master sensor & temperature is set to desired temperature. While carrying out the activity temperature of master sensor is noted & output of furnace thermocouple, temperature indicators etc are checked & compared with master sensor.


OVERVIEW
