HydroRanger 200 is an ultrasonic level meter launched by Siemens. It can realize liquid level measurement, level difference measurement and open channel flow measurement. It has built-in Modbus RTU, RS-485 digital communication interface, can use SmartLinx system and SIMATIC PDM configuration software, single or double point liquid level monitoring, 6 standard relays, automatic false echo suppression function for fixed interference targets, anti-oil ring / tidal trend recording, differential sensor input effectively improves the signal / noise ratio, wall mount and panel mount options and other features.
The HydroRanger 200 is an ultrasonic level transmitter that measures liquid level using ultrasonic waves. It offers a measurement range of 0.3‑15 m, analog inputs of 0‑20 mA or 4‑20 mA, digital inputs of 19‑50 VDC, and up to six relays (5 A / 250 VAC). The device includes built‑in Modbus FTU and RS‑485 communication, and supports optional Profibus DP and DeviceNet modules.
Installation is available in wall‑mount or panel‑mount configurations, with a stainless‑steel nameplate and cable‑entry kits. Power can be supplied from 100‑230 VAC (36 VA) or 12‑30 VDC (20 W). The unit meets CE, UL, CSA, FM, and ABS certifications and is suitable for water‑well, canal, and tank applications in harsh environments. This manual is written in Chinese.
