· The actual maximum working pressure must be less than the rated working pressure flowmeter.
· The maximum operating temperature and the minimum working temperature must meet the requirements specified temperature meter.
Determine whether there is the presence of negative pressure.

How to choose the inner diameter of the meter:

You can select the appropriate electromagnetic flowmeter according to how the correct selection table flow, bore electromagnetic flowmeter selected if the inner diameter of the process piping and now does not match, it should be reduced or expanded camps tube.
• If pipes shrink tube should be considered due to the reduction of the pressure loss caused will affect the process.
· From product price considerations, you can choose the smaller diameter electromagnetic flowmeter, relative reduced investment.
• When measuring clean water, economy flow rate is 2 ~ 3m / s, measured and crystallization of the solution, should be appropriately increase the flow rate, in order to prevent the electrode electromagnetic flowmeter is covered.

How to choose the protection level and additional instructions:

Protection class
In accordance with national standards and the International Electrotechnical Commission standard GB4208-84 IEC529-76 standards for housing protection rating as follows:
· IP65: anti-spray type, allowing the tap water from any direction sensor, water pressure is 30kPa, the amount of water is 2.5L / s, a distance of 3m.
· IP68: diving, long-term work in the water.
Protection rating should be selected according to the actual situation, the sensor mounted below ground, often affected by flooding should be used in IP68, the sensor is installed above ground should be used IP65.
Additional features
Basic LDB-type electromagnetic flowmeter has a display, output 4 ~ 20mA and 0 ~ 1kHz alarm function, selected additional functions can be added according to the actual situation.
· Split installation: The sensor must be installed below ground level or other reasons, you should choose split installation.
· RS-485 communications require sensors and other equipment communications, you need to choose RS-485 communication function.
How in the pipe installation:
· Should be installed in horizontal and vertical piping at lower upwardly, avoid installation at the highest point of the pipeline and vertically downward;
· Should be installed at the rise in the pipeline;
· In the opening discharge pipe installation and should be installed at the lower pipe;
· If the pipeline gap exceeds 5m, the sensor is installed downstream of the exhaust valve;
· Should install the sensor downstream of the control valve and shut-off valve, and should not be installed upstream of the sensor;
Import and Export Department • Sensor must not be installed in the pump should be installed at the outlet of the pump;

How to choose to install Node:
Select the correct mounting points and meters are very important part is correctly installed, if the installation link failure, the light affect the measurement accuracy, severe cases can affect the life of the meter, or even damage the meter.
When choosing the installation location require special attention:

Non-measurement axis electrodes must be approximately horizontal direction;
· Must be completely filled with liquid measuring pipeline;
· Meter front must have at least 5 * D (D as meter diameter) length of straight pipe sections, the rear must have at least 3 * D (D as meter diameter) length of straight pipe sections;
• Fluid flow direction and the direction of the arrow flowmeter is consistent;
· Have a vacuum inside the pipeline will damage the flowmeter liner, need special attention;
· In the vicinity should be no strong electromagnetic flowmeters;
· Near the meter should be plenty of space for installation and maintenance;
• If the measurement pipe vibration, in the mixed liquid on both sides of the meter should be fixed bearing different media when measuring the distance between the mixing point and the meter must have at least 30 * D (D as meter diameter) for the convenience of length flowmeter future cleaning and maintenance, should be installed bypass pipe;
· When installing Teflon lined flowmeter, connecting the two flange bolts should be noted that even tightened, otherwise easily crushed Teflon liner, preferably with a torque wrench.
