1. The core issues of electromagnetic flowmeter display screen not displaying numbers are generally concentrated in power supply, display module, signal transmission, parameter setting, or electromagnetic interference. Although the display screen can light up in terms of power supply, insufficient power supply voltage or poor contact may cause the numbers to not be displayed. You can first use a multimeter to check if the power supply voltage is within the rated range of the device, and check if there are any loose or oxidized wiring terminals. If necessary, replace the power supply circuit. If other functions are normal but there are no numbers on the screen, there is a high possibility of damage to the display module. It is recommended to directly contact the equipment manufacturer or after-sales service to confirm whether the module needs to be replaced, in order to avoid secondary damage caused by self disassembly. 3. Signal transmission issues such as open circuits, short circuits, or damaged shielding layers between sensors and converters can result in data transmission failure. A megohmmeter can be used to test the insulation of cables, check for loose joints, and prioritize using original shielded cables when replacing damaged cables. Improper operation of parameters or programs may result in incorrect parameter settings or program freezing. Try long pressing the device reset button to restore factory settings, and strictly follow the instructions to reconfigure parameters such as pipe diameter and range. If the reset is ineffective, the manufacturer needs to upgrade the firmware. If there are devices such as frequency converters and high-power motors in the surrounding area, strong magnetic fields can interf
2. What does t/h represent on the steam flow meter display screen?
The steam flow meter display screen shows t/h, which represents the mass flow rate of steam passing through per hour, in tons per hour.
. 1. The meaning of the single digit t is the abbreviation for ton in English, and h is the abbreviation for hour in English. t/h is the most commonly used unit of measurement for steam flow meters in industrial production, representing the mass (weight) flow rate of steam measured by the equipment per hour, and its value directly corresponds to the tonnage of steam passing through per hour. For example, if the displayed value is 10.5 t/h, it means that the current steam flow rate is 10.5 tons per hour. 2. Core application scenario: This unit is mainly used for energy management and cost accounting in the industrial field. Boiler room: monitors the steam output of the boiler. • Automobile room: Measure the steam consumption of production equipment (such as dryers, reactors, heat exchangers). • Energy settlement: As a key basis for internal cost accounting of enterprises or settlement of steam trade between different economic entities, steam is a compressible gas whose volume changes with temperature and pressure. Therefore, in industry, mass flow rate (tons/hour) is usually used instead of volume flow rate (cubic meters/hour) for measurement, which can more accurately reflect the actual amount of energy medium consumed and avoid calculation errors caused by parameter fluctuations. 『SILVER Official Website SERVICE』
