MTLD electromagnetic flow meter – Meter Mode

By Lanry Instruments on 23-09-11

Test mode: Supply power to the converter, the instrument get into the test mode (LCD middle row no battery symbol on the right side). The converter can output pulse signals to complete the machine calibration or change the converter parameters. After entering the meter calibration mode, without ...

MTLD battery operated electromagnetic flow meter’s characteristics

By Lanry Instruments on 23-09-11

(1) MTLD has high stability and measurement accuracy (up to 0.5 level); (2) Low power consumption : a standard battery can work for 3-6 years (determined by the excitation current); (3) Dual power supply: MTLD is equipped with external power supply interface, which can be powered by external 12-2...

Ultrasonic flowmeter solutions for certain liquids with air bubbles

By Lanry Instruments on 23-09-04

Q, when there are bubbles in the pipeline, is the ultrasonic flowmeter measurement accurate? A: When there are bubbles in the pipeline, if the bubbles affect the decline of the signal, it will affect the accuracy of the measurement. Solution: First remove the bubble and then measure. Q: Ultrasoni...

What is the reasons of ultrasonic flow meter with bad measurement result ?

By Lanry Instruments on 23-09-04

1. The influence of upstream and downstream straight pipe segment on the measurement accuracy of ultrasonic flowmeter. The calibration coefficient K is a function of Reynolds number. When the flow velocity is uneven from laminar flow to turbulent flow, the calibration coefficient K will change gr...

Installation notices-Clamp on pipeline ultrasonic flow meter

By Lanry Instruments on 23-09-04

1. Avoid the installation of the machine in the water pump, high-power radio, frequency conversion, that is, there is strong magnetic field and vibration interference; 2. Select the pipe should be uniform and dense, easy to ultrasonic transmission of the pipe segment; 3. To have a long enough str...

what points should we take care before installation ?

By Lanry Instruments on 23-09-04

Ultrasonic flowmeter is simply an instrument that measures the flow of liquid by detecting the effect of fluid flow on ultrasonic pulses. It is widely used in power station, channel, municipal industry and sewage treatment industry. The same as the electromagnetic flowmeter, the ultrasonic flowme...

Beverage factory application – Pure water flow measurement

By Lanry Instruments on 23-09-04

A beverage application – Pure water flow measurement Pure water supply line of the drinking water source. Because the #400 inner and outer surfaces of the polished sanitary pipe is relatively thin, ultrasonic wave propagation along the circumference of the pipe sometimes interferes with the...
