This helps to ensure that production equipment is properly cleaned and sanitized, protecting the safety and quality of the final products.
Overall, electromagnetic flowmeters are indispensable tools for measuring and controlling the flow of conductive fluids in a wide range of industrial and agricultural applications. Their accuracy, reliability, and versatility make them a valuable asset for any organization that relies on fluid flow measurement.
Environmental Conditions and Material Options for Magnetic Flowmeters:
When selecting a magnetic flowmeter for a specific application, it's important to consider the environmental conditions in which the meter will be operating, as well as the properties of the fluid being measured. Here are some key environmental conditions and material options to consider:
Environmental Conditions:
Ambient Temperature: The sensor of the magnetic flowmeter should be able to withstand temperatures ranging from -25°C to +60°C, while the converter should be able to operate within a range of -10°C to +60°C. These temperature ranges ensure that the meter can function reliably in a wide variety of environments.
Relative Humidity: The meter should be able to operate in relative humidity levels ranging from 5% to 95%. This high humidity tolerance is important for applications where the meter may be exposed to moisture or humid conditions.
Fluid Properties:
Fluid Conductivity: Magnetic flowmeters require the fluid to be conductive in order to measure its flow rate. The minimum fluid conductivity required for accurate measurement is typically greater than 5μS/cm. Tap water and raw water typically have conductivities ranging from 100μS/cm to 500μS/cm, which is well within the range of most magnetic flowmeters.
Material Options:
Electrodes: Magnetic flowmeters are available with a variety of electrode materials to suit different fluid properties and applications. The choice of electrode material depends on factors such as the fluid's corrosivity, temperature, and pressure. Common electrode materials include stainless steel, Hastelloy, tantalum, titanium, and platinum. Each material has its own unique properties and is suited for specific types of fluids and operating conditions.
Linings: The lining material of the flowmeter's measuring tube is also important, as it protects the electrodes and the meter's internal components from the fluid being measured. Different lining materials are available to suit a wide range of fluids, including corrosive and abrasive fluids. Common lining materials include rubber, PTFE (Teflon), ceramic, and epoxy resins. The choice of lining material depends on factors such as the fluid's chemical composition, temperature, and pressure.
By considering the environmental conditions and fluid properties of your specific application, you can select a magnetic flowmeter with the appropriate electrode and lining materials to ensure accurate and reliable flow measurement.
The corrosion-resistant electromagnetic flowmeter you described is a versatile instrument designed to accurately measure the flow rate of a wide range of fluids, including corrosive media and those with high hygiene requirements. Here are some key features and benefits of this type of flowmeter:
Corrosion Resistance:
The PTFE (polytetrafluoroethylene) lining provides excellent corrosion resistance, making the flowmeter suitable for measuring a variety of corrosive media such as acids, alkalis, and salts. PTFE is a non-reactive material that resists attack from most chemicals, making it an ideal choice for harsh environments.
Electrode Options:
The flowmeter offers a range of electrode materials to choose from, including 316L stainless steel, tantalum, titanium, Hastelloy, and platinum alloy. These materials have different corrosion resistance properties and are suited for specific types of fluids and operating conditions. For example, platinum alloy electrodes offer exceptional corrosion resistance and are often used in applications involving highly corrosive or abrasive fluids.
Integral Flange Connection:
Power Supply Options:
The flowmeter offers a choice of power supply voltages, including 220V and 24V. This flexibility allows the flowmeter to be used in a variety of power environments, making it suitable for a wide range of applications.
On-site Display with 4-20mA Output:
The on-site display provides real-time flow measurement readings, allowing operators to monitor the flow rate of the fluid being measured. The 4-20mA output signal allows the flowmeter to be integrated into a larger process control system, enabling remote monitoring and control of the flow rate.
High Hygiene Requirements:
In addition to measuring corrosive media, this flowmeter is also suitable for measuring fluids with high hygiene requirements, such as tap water, drinking water, wine, and fruit juice. The smooth, non-stick surface of the PTFE lining makes it easy to clean and sanitize, helping to prevent contamination and ensure the safety of the fluid being measured.
Overall, the corrosion-resistant electromagnetic flowmeter with PTFE lining, optional electrode materials, integral flange connection, and on-site display with 4-20mA output is a versatile and reliable instrument for measuring the flow rate of a wide range of fluids, including those with corrosive properties and high hygiene requirements.
