Flow out Sensor (Paddle) for mud logging unit

Flow out Sensor (Paddle) for mud logging unit The flow sensor uses the functional relationship between mud flow and baffle plate to reflect the change of baffle Angle displacement with the change of single coil potentiometer resistance value, so as to measure the relative change of mud flow.


The sensor is used to real time inspect the flow out of mud, so it provides a basis for optimized and safe drilling. According to the linear equation of liquid, the Bernoulli principle and the force analysis, the functional relation between flow out and angular displacement of mudguard can be acquired. Consequently, once the angular displacement is acquired, the flow out can be measured immediately.



Power supply voltage: 24VDC

Output signal: 4 ~ 20mA

Operating temperature: -55℃ ~ +100℃

Open Angle of damper: 0 ~ 45°

Measuring range: 0 ~ 100% (relative change, no absolute range)

Measuring accuracy: ± 2% FS

Overall size: 380 x 250 x 170 (mm)



Flow sensor can be divided into two parts, one is the mechanical part, the other is the circuit part. The mechanical part includes bottom plate, bending arm, baffle, large weight block, small weight block, shaft, protective cover, limit block, big gear, pinion, etc. The bottom plate, bending arm, baffle plate and protective cover are made of stainless steel, while the big gear and pinion gear are made of brass. Drilling mud export impact damper, drive the bent arm, bending the arm and shaft through a long screws, axle and wheel through a fixed screw clamp, so bent arm rotation, caused the shaft and the wheel rotation, big gear and small gear meshing together, pinion and potentiometer to turn the handle through a fixed screw clamp, which file is means the change of displacement into the change of the potentiometer resistance, reflects the export of mud flow change.



In order to prevent the alkaline corrosion of mud, this product adopts stainless steel structure, equipped with explosion-proof junction box, sealing capsule, sealing ring and other sealing parts, and separate the transmission mechanism from the electrical part, these measures increase the safety and durability of the sensor.  This product has the advantages of simple installation, compact structure, durability, easy maintenance, safety and explosion proof, etc. It is an important sensor in oil drilling and geological exploration.



All sensors either are EX type or are intrinsically safe. Zone barriers are installed in the Unit. Using well-known brand products at home and abroad, the sensors of mud logging unit have the advantage of technical and performance indicators. At the same time, the service life is long.

1.Why do you choose our company?

We are trading company, founded a perfect oil and gas equipment product supply chain. We have worked in the oil industry for about 10 years(follow ISO9001 standard).We will checked our mill every months to make sure their quality. The after-service are charged by ourselves.So we can reply any problem within 24 hours.


2. How can you guanranty your quality?

Every time we will inspect our factories first. This inspect will include the persons, the present products, their scale etc. If everything is ok, we will start to cooperate. During cooperation, we will go to the factories to test the products to guanranty the products has good quality. If it doesn’t meet our requirement, the goods will be refused.


3. Do you have price advantage?

For us, the quality is our first consideration. And the second consideration is the price. We couldn’t say we have the lower price, because of quality issue. We need to say we have the best price.
