Frequently Asked Questions
➤ How to choose the right pressure transmitter/level meter for my application?
Consider factors such as measurement range, medium characteristics (temperature, viscosity, corrosivity), process pressure/temperature, accuracy requirements, output signals (4-20mA, HART, etc.), installation environment, and budget.
➤ What is the accuracy of your pressure transmitter/level gauge?
Accuracy varies by model and calibration. Please refer to the specific product data sheet, which details technical specifications like ± 0.1%FS or ± 0.075%FS.
➤ Key installation points for transmitters?
Ensure proper pressure tapping point selection to avoid sediment/vortices, correct pipe venting, solid electrical grounding, and ensure ambient conditions are within operating limits.
➤ How to perform zero point/range calibration?
Calibration can often be done locally via buttons/LCD or remotely using HART controllers. Specific steps vary by model; please consult the operation manual for the precise procedure.
➤ Which communication protocols are supported?
Supported protocols typically include HART (4-20mA), Profibus PA, and Modbus RTU/TCP. Please check your specific product data sheet for confirmation.
➤ What to do if the instrument display shows errors?
Consult the "Error Code" section of your manual first. Check power/wiring, verify process limits, and ensure sensors are clean. If issues persist, contact our technical support with the specific error code.
