The Turbine Flowmeter manufactured in 1978

On a hot summer day of 2021, Kaifeng Instrument Co., Ltd. welcomed a special guest to our CNAS/ISO17025 certified calibration lab, this special guest is a piece of turbine flowmeter manufactured by Kaifeng Instrument Co., Ltd. back in August 1978.

As it is shown in the picture below, the turbine meter’s model is LW-40, the flow unit is in m3/h, and the most important part is the date of manufacture, which is engraved 78.8, it stands for 1978, August.

After checking our internal documents of the flowmeter, and talking to the client, this turbine meter was used to measure the diesel oil consumption in their manufacturing unit. The flowmeter’s accuracy is plus/minus 0.2%.

The client mentioned this meter has been in operation without an issue since last century, but because it has been a long time, they needed to get the meter verified for future use. As the client requested, we carried out verification procedures for the diesel turbine flowmeter using the oil rig which we specifically build for calibration of oil flow meters.

After a couple of hours, the verification results came out and the meter is still functioning without an issue, the accuracy, repeatability, and pressure testing all meet the CNAS standards!

The client is very happy with the results and he said for all future projects involving flowmeters, they will always use Kaifeng Instrument Co., Ltd.’s product.

Kaifeng Instrument Co., Ltd., making flow profit for you.
