Hydrotechnik UK announce extended Calibration Department
Hydrotechnik UK has unveiled a major new addition to its existing calibration department. A brand new £100,000+ flow test rig enables Hydrotechnik to offer full in house flow meter recalibrations traceable to National Standards.
The new rig runs on oil, a major advantage for the company’s hydraulic, lube and diesel use customers. The oil’s viscosity is adjusted from 15 to 100cst with 32cst being the norm. A 5 point calibration is standard although 10 or more points throughout the measuring range can be performed on request. The rig has a flow range of 0.05L/min up to 700L/min and has 2 master flow meters giving a maximum uncertainty of +/-0.5%
Hydrotechnik has created a dedicated in-house laboratory room which caters for Flow, Pressure, Temperature and Oil Particulate sensors as well as instrumentation calibrations, re-calibrations and repairs. Pressure sensor calibration is from 0 – 1,200 Bar and Temperature from -50 to 200°C, all traceable to UKAS standards.
What is calibration?
Calibration is a testing procedure used to make sure that the current tolerance, accuracy and functionality of a sensor such as pressure, flow and temperature sensors are within acceptable parameters.
Why is it so important?
Re-calibration is an important periodic procedure as it ensures that a given sensor is producing reliable, safe and trustworthy results traceable to a known National Standard.
How often should I calibrate?
There is no one universal rule that dictates how often an instrument or sensor should be calibrated, there are, however, some broad factors that should be considered:
Calibration regulatory bodies
The leading calibration regulatory body in the UK is UKAS who certify organisations who meet set guidelines. UKAS examine both the organisation’s equipment and the procedures carried out to calibrate instruments. Similar bodies exist across Europe such as DKD in Germany.
Hydrotechnik UK has invested in a range of UKAS and traceable calibration equipment. From our temperature controlled flow meter testing rig to a new dead weight pressure tester and state of the art temperature bath.
Michael Sharpe, calibration Service Manager at Hydrotechnik UK, oversees day to day calibration at Hydrotechnik UK and recognises the benefits of new equipment: “The new equipment enables us to accurately calibrate flow meters, pressure, temperature, analogue and digital gauges, displays and data loggers to national, UKAS and DKD traceable standards.”
Providing this service in-house enables Hydrotechnik UK not only to meet its own and its sister companies calibration needs but to meet customers’ expectations for a cost-effective service and quick turn around on critical projects. In addition, Hydrotechnik can offer instrumentation repairs and functionality checks and, through its sister company Filtertechnik offer particulate monitor/tester re-calibrations.
