How to choose a right electromagnetic flowmeter for your application?
?? When it comes to selecting an Electromagnetic Flowmeter, there are several important factors to consider. Here are five key points to keep in mind:
1?? Conductivity Matters: electromagnetic flowmeters are ideal for measuring electrically conductive liquids such as water, wastewater, acids, alkalis, slurries, and more. Ensure that the liquid has a minimum conductivity of 10 μS/cm. Remember, they are not suitable for measuring hydrocarbons and gases.
2?? Consider Process Parameters: Take into account the working temperature, pressure, and velocity of your application. The temperature determines the suitable liner material, which provides insulation and resistance to corrosion and abrasion. Various liner options are available such as Hard Rubber and PTFE, based on temperature ratings. Also, specify the flow rate and velocity for accurate sizing.
3?? Determine Output Requirements: Decide the type of output you need from the flowmeter. The most common option is a 4-20 mA analogue current output for industrial use. For volume measurement, pulse output is suitable, and it can be converted into standard engineering units. Other output options include RS-485, RS-232, GSM, and GPRS, depending on communication needs.
4?? Power Supply Considerations: Check if electric power is available at the installation site. If not, battery-powered flowmeters can be a suitable option for remote locations. Battery life typically ranges from 5 to 10 years. Otherwise, choose between 24 V DC or 230 V AC power supply based on your application requirements.

5?? Balance Cost and Performance: Consider both cost and performance factors. Look for flowmeters that offer good accuracy, reliability, and minimal maintenance. Electromagnetic flowmeters have no moving parts, ensuring longevity and accurate measurements. They are particularly recommended for applications that require high accuracy.
Remember, the selection process for an electromagnetic flowmeter can be complex due to various variables. To ensure the right choice, you can consult our experts. ????
