The Zhongneng mud flowmeter is specially designed with a Chinese LCD display with backlight wide temperature range, which is fully functional, practical, intuitive, and easy to operate, reducing the inconvenience caused by the English menu of other mud flowmeters. In addition, we have designed a 4-6 multi electrode structure to further ensure measurement accuracy and eliminate the need for grounding rings at all times, reducing the size of the instrument and the trouble of installation and maintenance. The measurement accuracy is not affected by changes in fluid density, viscosity, temperature, pressure, and conductivity. The induction voltage signal of the medium energy mud flowmeter sensor is linearly related to the average flow rate, therefore the measurement accuracy is high. The mud flowmeter measures that there are no obstructions in the pipeline, so there is no additional pressure loss; There are no movable parts inside the measuring pipeline, so the sensor has an extremely long lifespan. Due to the fact that the induced voltage signal of the Zhongneng mud flowmeter is formed in the entire space filled with magnetic field and is the average value on the pipeline surface, the sensor requires a shorter straight pipe section, with a length of 5 times the diameter of the pipeline. The sensor part only has the inner lining and electrodes in contact with the measured liquid. As long as the electrode and inner lining materials are selected reasonably, they can be corrosion-resistant and wear-resistant.

How to correctly select a Zhongneng mud flowmeter:
The selection of instruments is a very important task in instrument applications. Relevant data shows that 2/3 of instrument failures in practical applications are caused by incorrect selection or installation of instruments. Please pay special attention.
◆ Zhongneng Mud Flow Meter collects data
1. Composition of the tested fluid
2. Maximum and minimum flow rates
3. Maximum work pressure
4. Maximum and minimum temperatures
The measured fluid of the Zhongneng mud flowmeter must have a certain conductivity, with a conductivity>5 μ S/CM
The maximum and minimum flow rates of the mud flowmeter must comply with the numbers in the following table:

The actual maximum working pressure of the Zhongneng mud flowmeter must be less than the rated working pressure of the flowmeter. The maximum and minimum operating temperatures of the Zhongneng mud flowmeter must comply with the temperature requirements specified by the flowmeter. Determine if there is a negative pressure condition present in the medium energy mud flowmeter. You can choose the corresponding electromagnetic flowmeter based on the flow rate in the table above. If the inner diameter of the selected flowmeter does not match the current inner diameter of the process pipeline, it should be shrunk or expanded. If the pipeline undergoes shrinkage, consideration should be given to whether the pressure loss caused by shrinkage will affect the process flow.
From the perspective of product price, smaller caliber electromagnetic flow meters can be chosen to relatively reduce investment. When measuring clean water, the economic flow rate is 1.5-3m/s. When measuring solutions that are prone to crystallization, the flow rate should be appropriately increased to 3-4m/s to achieve self-cleaning and prevent adhesion and sedimentation; When measuring abrasive fluids such as slurry, the flow rate should be appropriately reduced to 1.0-2m/s to reduce wear on the lining and electrode. Actual applications rarely exceed 7m/s, and exceeding 10m/s is even rarer.

Correct wiring of Zhongneng mud flowmeter:
① The excitation cable of the Zhongneng mud flowmeter can be selected as YZ medium-sized rubber sheathed cable, which has the same length as the signal cable
② The signal cable of the Zhongneng mud flowmeter and other power cables must be strictly separated and cannot be laid in the same pipe, parallel, or twisted together. They should be separately threaded in steel pipes.
③ The signal cable and excitation cable of the Zhongneng mud flowmeter should be kept as short as possible, and excess cables should not be coiled together. The excess cables should be cut off and re welded. When the cables enter the sensor electrical interface, they should be made U-shaped at the port to prevent rainwater from penetrating into the sensor.
④ The connection between the excitation cable and the converter of the Zhongneng mud flowmeter split type mud flowmeter is completed with dedicated wiring, and the converter and external connection are the same as the integrated mud flowmeter.

Should be installed at the rising point on the pipeline;

When installing an open discharge pipeline, it should be installed at the lower part of the pipeline;

If the pipeline drop exceeds 5m, install an exhaust valve downstream of the sensor;

Control valves and shut-off valves should be installed downstream of the sensor, rather than upstream of the sensor;

Sensors should never be installed at the inlet and outlet of the pump, but rather at the outlet of the pump;

Method of installing flow meters in measuring wells

Special attention should be paid when selecting the installation location:

·The axis of the non measuring electrode must be approximately horizontal;

·The measuring pipeline must be completely filled with liquid;
