Packaged Water Level Station

53905390/A25390WL wireless5890 / 5890/A2 two-way →

Stream stage, reservoir and channel level from a complete, self-contained station. A submersible pressure transducer on a 40 ft vented cable measures the water column above it; every change is reported in real time over your ALERT or ALERT2 network.

You must specify at order

Radio: Maxon 5 W standard; Ritron 5 W or 30 W specify
Your licensed operating frequency specify

Accuracy class, ±0.10 to ±1.0% FSO specify

Rule of thumb: 1 PSI ≈ 2.31 ft of water. How to pick a range.

Which variant do I need?

If your site…	Order	Why
Joins an ALERT2 network (or is new)	5390/A2	Current NHWC standard — collision-free reporting, error correction
Joins an existing legacy ALERT network	5390	Matches your current receivers; upgradeable later
Needs remote polling or gate/pump control	5890/A2	Same station on the two-way 50388 SCADA platform — 5890 details →
Can't run a cable from station to sensor	5390WL	Wireless Lynx — a spread-spectrum radio pair links an SDI-12 transducer to the station, with solar power and an 18 Ah battery at the sensor site
