Supply YEH-X type ultrasonic level meter \ intelligent electronic level meter / gauge manufacturers

YEH-X ultrasonic level meter users self-test: A, the instrument is the most simple test method: Turn adequate power supply for the ultrasonic transmitter mouth open wide vertically aligned wall (fairly level) as a reflection of ultrasonic waves surface while observing the air L (L can continuously press the Shift key to view) figures, when the digital display L and the actual distance was described measurements often Description: 1, the inspection process should be noted: When the actual air L meter distance exceeding the maximum measurement distance L, considered invalid. 2, under normal circumstances, the blind range of the instrument d + C = meter maximum measurement distance L (max). 3, meter range and output current P d is related to the parameters, and other unrelated. B, the ultrasonic transmitter to the open mouth of the sky, one minute less than the meter should show F00F, in principle, said meter at this time there is no echo received, indicating a good anti-jamming performance of your meter. C, press Shift key to find P (Instrumented should output current) to directly measure the output current with the ammeter and P values ??should be fairly described output is normal. After testing more than three items, users can rest assured that use. YEH-X ultrasonic gauge basic parameters and functions: 1, the signal output → 4 ~ 20mA standard or optional 2 485,232, ranging capability → commonly known 4,7,10,12,15,17,20 m range and power. 50m 3, launch full-→ 7 ° is proportional to the size and range capability ~ 12 ° emission angle. 4, the mode → measurement distance L and H mode transition measure level, menu options. 5, blind → 0.25 ~ 1.0m → blind spots inherent in the menu to be investigated. 6, the resolution → measuring distance <10m → 1mm. Measuring distance ≥10m → 10mm 7, protection class → Ip66. 8 ,, precision → 0.5%. 9, the ambient temperature → -15 ~ + 55 ℃.
