1. Precautions for installation of split type electromagnetic flowmeter
Precautions for installation of split type electromagnetic flowmeter: Multiple aspects need to be paid attention to during the installation of split type electromagnetic flowmeter to ensure its accurate and stable operation. Here are some key precautions:
1. Grounding of the sensor: In order to ensure the reliable operation of the split electromagnetic flowmeter, improve measurement accuracy, and avoid interference from external parasitic potentials, the sensor should have a good separate grounding wire.
. The grounding resistance should be less than 10 Ω to ensure good grounding effect. Non metallic pipeline treatment: If there is a flame retardant coating or non-metallic pipeline inside the pipeline connecting the sensor, special attention should be paid to grounding issues. In this case, additional grounding measures may need to be taken to ensure that the potential difference between the sensor and the pipeline does not interfere with the measurement results.2. Requirements for external environment temperature changes: Flow meters should be avoided from being installed in places with large temperature changes or exposed to high temperature radiation from equipment.
. If it is necessary to install in these environments, insulation and ventilation measures should be taken to reduce the impact of temperature changes on the flow meter. Rain and sun protection: It is best to install the flow meter indoors. If it must be installed outdoors, it should be avoided from being drenched by rainwater, flooded with standing water, and exposed to sunlight. For this, moisture-proof and sun protection measures need to be taken, such
III. Requirements for bypass pipe for easy maintenance: In order to facilitate the maintenance of the flowmeter, it is best to install a bypass pipe for the flowmeter.
. In this way, when it is necessary to maintain the flowmeter, fluid can continue to be delivered through the bypass pipe without interrupting the entire fluid system. Cleaning requirements: For heavily polluted fluids and flow meters that require cleaning but cannot be stopped, a bypass pipe must be installed. This helps to maintain the normal operation of the fluid system when cleaning the flowmeter. In summary, during the installation process of a split type electromagnetic flowmeter, attention should be paid to
