Wata Mito Masanin

Wata Mito Displacement Positi

Wadannan mito suna cewa yadda ruwa ya cuta tun daga wurin da aka raba da shi da kuma yadda zaka ce. Wannan shine mafi yawan da ka fada ruwan da ake raba da shi zuwa darajar da yake da shi kuma ba tana basu.

Wadannan mito suna iya cewa yadda cututukan da ke da damar da kuma yadda abubuwa da ke da damar. Wadannan mito suna iya gudanar da tsawon ruwan bai da damar ko tsari. Wadannan mito suna da kyau saboda ban da nasara da tsawon kaya a kofin ruwa.

Nutating disc meter, Reciprocating piston meter, Oscillatory or Rotary piston meter, Bi-rotor type meters like those of Gear meter, Oval gear meter (Figure 1) and Helical gear meter fall under this category.

Wata Mito Massa

Wadannan mito suna cewa yadda abubuwa ya cuta tun daga wurin da aka raba da shi. Suna amfani da su a masanin kimiyar da ake bukatar cewa yadda abubuwa ya cuta yana da muhimmanci da yadda abubuwa ya cuta.

Thermal meters (Figure 2a) and Coriolis flowmeters (Figure 2b) fall under this category. In the case of thermal meters, the fluid flow cools-off the probe, which is pre-heated to a certain degree. The heat loss can be sensed and will be used to determine the rate at which the fluid will be flowing.

 On the other hand, Coriolis meters work on the principle of Coriolis principle in which the fluid flow through the vibrating tube causes a change in frequency or phase shift or amplitude, which gives a measure of its flow rate.

Wata Mito Differential Pressure

Wata mito differential pressure suna cewa yadda abubuwa ya cuta tun daga wurin da aka raba da shi da kuma yadda zaka ce. Idan abubuwa ya cuta, zaka ce a kan kofin da ke da damar, wanda mito suna rarrabe. Yadda abubuwa ya cuta ana da damar da square root da zaka ce, idan an yi kamar hukumar Bernoulli.

Orifice plate meter, Flow nozzle meter, Flow tube meter, Pilot tube meter, Elbow tap meter, Target meter, Dall tube meter, Cone meter, Venturi tube meter, Laminar flow meter, and Variable Area meter (Rotameter) are a few examples of differential pressure flow meters.

Wata Mito Velocity

Wata mito velocity suna cewa yadda abubuwa ya cuta tun daga wurin da aka raba da shi da kuma yadda zaka ce. Yadda abubuwa ya cuta ana da damar da yadda abubuwa ya cuta. Wadannan mito suna iya cewa yadda abubuwa ya cuta tun daga wurin da aka raba da shi da kuma yadda zaka ce, kamar turbines.

Depending on the way used to find out the velocity, we have various kinds of velocity flow meters like Turbine flow meter, Vortex Shedding flow meter, Pitot tube flow meter, Propeller flow meter, Paddle or Pelton wheel flow meter, Single jet flow meter and Multiple jet flow meter.

Flow rate measurement of fluids in hazardous environments, including those in the case of mining demands for the non-intrusive flow meters. SONAR flow meters which are a type of velocity flow meters serve this kind of requirements. Besides, ultrasonic flow meters, as well as electromagnetic flow meters, also form a part of velocity-type flow meters.

Wata Mito Na Nuna

Wata mito na nuna suna amfani da nuna wajen cewa yadda abubuwa ya cuta. Suna amfani da laser beam da photodetectors. Gas particles scatter the laser beam to create pulses detected by the receiver. By measuring the time between these signals, the speed of the gas can be determined.

As these meters measure the actual speed of the particles constituting the gases, they remain unaffected by the thermal conditions and the variations in gas flow. Hence, they are capable of providing highly accurate flow data even when the environment is most unfavorable, say, for example, when we have high temperature and pressure, high humidity, etc.

Wata Mito Tafin Kusa

Wata mito tafin kusa suna amfani da su wajen cewa yadda abubuwa ya cuta tun daga wurin da aka raba da shi da kuma yadda zaka ce. Weir meters and Flume meters (Figure 6) are the open channel flow meters which use secondary devices like bubblers or float to measure the depth of the fluid at a particular point. From this depth, the flow rate of the fluid can be obtained.

On the other hand, in dye-testing based open channel flow measurement case, a certain predetermined amount of dye or salt is used to change the concentration of the flowing stream of the fluid. The resulting dilution gives a measure of flow rate of the fluid. Next, it is to be noted that the precision with which the flow meters need to operate is decided by the application for which they are used. 

For example, when we want to monitor the flow of water through a pipe in our garden, it would be enough if we use a flow meter which has a lower precision than that which will be used when we need to monitor the flow of an alkali meant for a chemical process. Besides, one more factor which requires to be noted is that the flow meters, when used in conjunction with the flow valves, can perform the controlling actions successfully.
