water flow meter

QTLD water flow meter is calibrated by ISO/IEC 17025:2016 CNAS Approved Test Bench.

Sensor protect grade of split magmeter is IP68, it can be submerged in the water or buried underground.

Standard material of waste water flow meter is carbon steel, but client can chose stainless steel 304 or SS316.

QTLD PTFE lining material has been approved NSF and FDA.

waste water flow meter magmeter is calibrated by MT methoud water flow standard calibration device, mass method, comparison method and pulse method can be used, standard accuracy is ¡À0.5%, ¡À0.2% accuracy is optional.

Q&T Instrument are OEM for some European and American clients, we have strick control, like high and low temperature test for transmitters, pressure test, etc.

electromagnetic flow meters are calibrated by Mass Method liquid calibration equipment, which is approved by CNAS ISO 17025, which is mutual recognition by ilac-MRA

magnetic flowmeter is installed to measure water contains particles, it can influence the measurement, our slurry magnetic flow meter adopts square wave excitation and 25Hz/30Hz high excitation, which can eliminate interfacerence between the sharp wave noise generated by solid particles, ensures accurate measurement of viscous medium.

The electromagnetic flowmeter is to measure chemical conductive liquids. the electromagnetic flowmeter has function of high and low alarm, excitation alarm, empty pipe alarm, self-diagnosis.

water flow meter is widely used because less obstruction, cost-effective and accurate measurement. Magnetic flow meter don’t have any moving parts to wear down, reducing the need for maintenance or replacement.

water flow meter is calibrated by stainless steel liquid test bench, mag flowmeter is calibrationed 5 points. we have 8 sets of liquid flow meter to calibrate mag flowmeter.

water flow meter can be calibrated 8 pcs at the same time, while 5 points flow will be calibrated, all test bench has been approved ISO 17025.

water flow meter are calibrated 5 points by Mass Method liquid calibration equipment, all test bench are stainless steel.

A handheld ultrasonic flowmeter is a low-cost portable device with a sensor for non-invasive liquid flow measurement. This handheld ultrasonic flowmeter utilizes proven time difference ultrasonic measurement technology for excellent accuracy and ease of setup and installation.
This easy-to-use flowmeter comes with a sturdy, waterproof carrying case that allows easy transport of the display, sensor, and cables between measurement locations.
