Float flow meter

By Lanry Instruments on 22-09-13

Float flowmeter, also known as rotor flowmeter, in a vertical tube with a conical inner hole expanding from bottom to top, the weight of the float is borne by the force generated by the bottom-up fluid, and the position of the float in the tube to represent the flow value of variable area flowmet...

What is the class of ultrasonic water meter ?

By Lanry Instruments on 22-09-13

Water meter’s accuracy is graded for Class 1 and 2. 1) Class 1 water meters (only applicable to Q3≥100m3/h water meters) in the water temperature range from 0.1℃ to 30℃, the maximum allowable error of water meters in the high zone (Q2≤Q≤Q4) is ±1%; The low area (Q1≤Q < Q2) was ±3%. ...

The typical applications of Doppler flowmeter

By Lanry Instruments on 22-09-05

Doppler ultrasonic flowmeter is specially designed for the measurement of solid particles or bubbles and other impurities or dirty liquids. It is mainly applied in the following fields: 1) Raw sewage, oily sewage, waste water, dirty circulating water, etc. 2) Industrial production process ...

the typical applications of transit time ultrasonic flow meter

By Lanry Instruments on 22-09-05

Transit time ultrasonic flowmeter is suitable for measuring pure liquid in closed pipe and the content of suspended particles or bubbles in the measured liquid is less than 5.0%. Such as: 1) Tap water, circulating water, cooling water, heating water, etc.; 2) Raw water, sea water, sewage a...

Advantages and Disadvantages of Doppler Flowmeters

By Lanry Instruments on 22-09-02

Although Doppler ultrasonic flowmeter is not so accurate as transit time ultrasonic flow meters, Doppler flowmeter can measure dirty liquids ( but it cannot measure clean liquids ), Doppler flow meter can measure sewage flow because sewage is with a lot of solids, at the same time, it is also mea...

Mount the TF1100 clamp on flow transmitter in a location that is:

By Lanry Instruments on 22-09-02

♦ Where little vibration exists. ♦ Protected from falling corrosive fluids. ♦ Within ambient temperature limits -20 to 60°C ♦ Out of direct sunlight. Direct sunlight may increase transmitter temperature to above the maximum limit. 3. Mounting: Refer to below picture for enclosure and mounting dim...

Clamp on ultrasonic flowmeter- Zero points

By Lanry Instruments on 22-09-02

Set Zero, when the fluid is in the static state, the displayed value is called “zero point”. When the “Zero Point” is not really at zero, the incorrect read value is going to be added into the actual flow values. Generally speaking, the lower the flow rate, the higer the error . Set Zero must be...
