What is the difference of clamp on ultrasonic flowmeter, inline ultrasonic water meter, insertion ultrasonic flowmeter ?
Different types meter have different advantages . 1 Clamp on ultrasonic flow meter No need to cut the pipe and interrupt process ; Clamp on transducers are just clamped on pipe wall, easy to install ; 2.Inline ultrasonic water meter It can measure the pipe of sparse material , poor acoustic cond...Read more -
What are the advantages of ultrasonic technology smart water meters ?
Ultrasonic water meter is a smart water meter of inline flow measurement by the working principle of ultrasonic transit-time. It includes thread and flange connection water meter and its has many advantages as below . 1) Single channel or double channels water flow measurement, higher accuracy,...Read more -
Why does clamp on ultrasonic flow meter show weak signal when during flow measurement ?
Clamp on ultrasonic flow meter is suitable for flow measurement in full water pipe, it is easy to install and no contact with liquid directly; It can measure the medium that is not easy to touch or observe. Usually, ultrasonic flowmeter clamp on can work for very long time. When the poor signal...Read more -
Float flow meter
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...Read more -
What is the class of ultrasonic water meter ?
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%. ...Read more -
The typical applications of Doppler flowmeter
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 ...Read more -
the typical applications of transit time ultrasonic flow meter
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...Read more -
Advantages and Disadvantages of Doppler Flowmeters
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...Read more -
Mount the TF1100 clamp on flow transmitter in a location that is:
♦ 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...Read more -
Clamp on ultrasonic flowmeter- Zero points
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...Read more -
4-20mA output introduction
Many industrial meters choose to use current to transmit signals, because current is not sensitive to noise. The current loop of 4 ~ 20mA is 4mA to represent the zero signal, 20mA to represent the full scale of the signal, and the signal below 4mA and above 20mA is used for the alarm of various ...Read more -
Why is the 4-20MA signal used in industry and not the 0-20MA signal?
The most widely used standard analog quantity electrical signal in industry is to transmit analog quantity with 4~20mA DC current. The reason for using the current signal is that it is not easy to be interfered with, and the internal resistance of the current source is infinite. The wire resista...Read more
