The ZRN-100Y pipe section ultrasonic flowmeter adopts a flange connection method, which integrates the ultrasonic sensor and the conduit into an integrated ultrasonic flowmeter for easy on-site installation.

Technical parameters

*Measurement accuracy: better than 1%, repeatability: better than 0.2%

*Measurement cycle: 500ms (2 times per second, 128 sets of data collected per cycle) ZRN-100Y tube segment ultrasonic flowmeter is a sealed casing that connects the ZRN-100Y-18 motherboard to a 20 wire 4-point parallel port keyboard display for online display and operation. This product avoids errors caused by human and pipeline factors during the installation of external and plug-in sensors. It has the advantages of high precision, wide range ratio, no pressure loss, and simple installation.

*Display: 2 × 10 Chinese character backlit display (bilingual options available in Chinese and English)

*Operation: Magnetic 4-point windowed operation

*Signal input: ◇ 3-channel 4-20mA analog input, accuracy of 0.1%, can input pressure, liquid level, temperature and other signals

◇ 2-channel three wire PT100 platinum resistor

*Signal output: ◇ 1 isolated RS485 output

◇ 1-channel isolated OCT (programmable pulse width between 6-1000ms, default 200ms)

◇ 1 relay output (pulse width 200ms)

◇ 1 4-20mA output (active/passive output optional)

◇ 1 bidirectional serial peripheral universal interface, which can directly connect multiple external devices (such as sea data storage modules, etc.) through serial connection

*Communication protocols: MODBUS protocol, M-BUS protocol, FUJI extension protocol, and compatible with communication protocols of similar products from other domestic manufacturers

*Connection method: flange type/union type (sanitary type) optional

*Other functions: ◇ Automatically remember the first 512 days, the first 128 months, and the positive/negative/net cumulative traffic of the first 10 years

◇ Automatically remembers the first 30 power on/off times and flow rate, and can achieve automatic or manual replenishment. It can be read out through the MODBUS protocol

Code files that can be transmitted via email for software upgrade
