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 -
Magnetic flowmeter introduction
Electromagnetic flowmeter Electromagnetic flowmeter is a kind of induction meter which is made according to Faraday’s law of electromagnetic induction to measure the volume flow of conductive medium in the tube. In the 1970s and 1980s, the electromagnetic flow has made a great breakthr...Read more -
vortex flow meter introduction
Vortex flowmeter Vortex flowmeter is an instrument in which a non-streamlined vortex generator is placed in the fluid, and the fluid alternately separates and releases two series of regular staggered vortices on both sides of the generator. Vortex flowmeter is one of the youngest flowmeters, but...Read more -
Coriolis mass flowmeter introduction
Coriolis mass flow meter is a direct mass flow meter made of Coriolis force principle which is proportional to the mass flow rate when the fluid flows in a vibrating tube. Can be used for liquid, slurry, gas or steam mass flow measurement. Overview of Application: Mass flowmeter not only h...Read more -
Ultrasonic flowmeter
As ultrasonic waves travel through a moving fluid, they carry information about the velocity of the fluid. Therefore, the received ultrasonic wave can detect the flow rate of the fluid, which can be converted into flow rate. According to the detection method, it can be divided into different ty...Read more -
The ultrasonic flowmeter can be installed according to the following steps:
The ultrasonic flowmeter can be installed according to the following steps: 1. Observe whether the pipeline at the installation site meets the distance requirement, it asked upstream 10D and downstream 5D, D is pipe size. Even if we can not ensure 10Dand 5D, at least upstream 5D and downstream ...Read more
