Ultrasonic flowmeter selection illustrates: ZRN-100F1-AN-B2-200-0-1.6-MK-4-N-10
Explanation: The Wall hosts, AC power supply, M1 standard probe, DN200 diameter, carbon steel pipe, pressure 1.6MPa, flow units cubic meter, 485 output.
10 m cable.
Notes explain:
① : * AC power applied to ZRN-100F type, ZRN-100Y type, other models hosts for battery-powered or DC power supply.
* DC power supply for all models, in addition to ZRN-100F1, F2, F3, ZRN-100S power is 24VDC, the rest is 8-36VDC.
* ZRN-100W battery-powered meter can also 8-36V power supply, please indicate if required when ordering.
② : Battery-powered ultrasonic flowmeter, industrial water / heat meters, such as the choice of plug-in or clamp-on sensors, the maximum measurable diameter is DN800.
③ : Cast iron, glass, steel, PVC, cement and other non-welded pipes such as the selection plug-in sensor, to be equipped with a dedicated pipe hoop before installation, please specify when ordering.
④ : The minimum reading only applies to ZRN-100W battery-powered ultrasonic water meter selection.
⑤ : * If you choose active 4-20mA output, the power supply requirements AC or DC 24V.
* OCT pulse width factory default settings 200ms, between 6 ~ 1000ms programmable.
* Battery-powered ultrasonic water meter or heat meter RS485 output, there are two options, one is the internal battery, operating voltage of 3.3V, and the other is
Require external DC power supply provided, please indicate when the user ordering, or they may output interface 485 is invalid.
