Product Overview
The Telog PR-32A is Badger Meter’s wireless, battery-powered single-channel pressure RTU — you connect it to a distribution main and it logs water-system pressure to local memory, running standalone with no site power and no network (up to about five years on a battery pack at one call a day). The same channel can read water level instead — aquifers, surface reservoirs, tank and tower levels — with the sensor set in a 2 in. well. That makes it the field tool for pressure-zone surveys and hydraulic-model calibration, where you place recorders across a system, let them run, and collect the data on a schedule. The PR-32iA option adds high-speed transient-waveform capture — to 256 samples per second — for surge and water-hammer transients a standard logger would miss. You collect locally over RS-232, or its integral cellular (CatM1 / Cat 1 LTE) modem calls a Telog host on a schedule or on alarm — feeding the Telog RM cloud, Telog Enterprise or Telogers for Windows.
Key Features & Benefits
- Years of standalone logging — battery-powered and self-contained — up to about five years between battery changes at one call/day on the PR-32A
- Pressure or level — one channel that monitors water-system pressure or level — aquifers, reservoirs, tank and tower levels — from a sensor that drops into a 2 in. well
- Impulse option for transients — the PR-32iA samples to 256/sec and stores the transient waveform — surge and water-hammer events that slip past routine interval logging
- Collect on your schedule — download locally over RS-232, or let its integral cellular (CatM1 / Cat 1 LTE) modem send the readings live
- Cloud or call on alarm — the cellular modem calls a Telog host on a schedule or on an alarm condition — Remote Monitoring Software, Telog Enterprise or Telogers for Windows
- One sealed IP68 unit — modem, antenna, signal conditioning, recorder and battery in a single NEMA 6P polycarbonate housing — nothing external to mount on the main
Specifications
- Function
- Wireless, battery-powered single-channel pressure RTU that logs to local memory — for distribution-pressure surveys, water-level monitoring, and hydraulic-model calibration
- Measures
- Water-system pressure, or water level — aquifers, surface reservoirs, and tank / tower levels (single channel)
- Variants
- PR-32A standard; PR-32iA adds the impulse option — high-speed transient-waveform capture (to 256 samples/sec) for surge and water-hammer studies
- Recording & memory
- Logs to local memory and runs unattended without a network; user-set intervals, wrap-around (first-in/first-out) storage
- Power
- User-replaceable Telog BP-4 lithium battery pack — up to ~5 years at one call/day on the PR-32A (PR-32iA battery life depends on the sampling rate)
- Telemetry / download
- Local download over RS-232 (4-pin circular, auto-baud to 19.2K), or its integral cellular (CatM1 / Cat 1 LTE) modem calling the host on a schedule or on alarm
- Outputs
- Local RS-232 download and an internal cellular modem to a Telog host — Remote Monitoring Software, Telog Enterprise or Telogers for Windows
- Enclosure / protection
- IP68 / NEMA 6P polycarbonate housing with integral antenna, modem and battery (single unit)
- Mounting
- Connects to a distribution main; the pressure sensor installs in a 2 in. well
- Platform compatibility
- Optional Telog RM cloud; standalone otherwise
Common Applications
- Water-system pressure-zone surveys across a distribution network
- Water-level monitoring — aquifers, surface reservoirs, and tank / tower levels
- Hydraulic-model calibration with logged field pressures
- Surge and water-hammer studies (with the PR-32iA impulse option)
Design & Selection Considerations
- Log locally first — no power or signal required — every Telog device records to local memory and runs standalone indefinitely, so a site keeps recording even with no power and no network. Connectivity is optional at the start — a standalone logger can be promoted to live telemetry later without re-engineering.
- Recorder or cellular RTU? — battery recorders (HPR-32A, PR-32A, RG-32A) suit surveys and temporary studies you collect on a schedule; cellular RTUs (Ru-32, Ru-35, RS-45) transmit to the Telog RM cloud for permanent, real-time monitoring and alarming. Recorder for portable or temporary work; RTU for fixed sites you watch continuously.
- Match power and housing to the site — choose a multi-year lithium battery, solar, or AC power, and an IP68 submersible housing for vaults and sewers. The RS-45 runs continuous AC/solar duty; the Ru-35 is the submersible choice. Power and ingress rating decide where a site can go — spec them with the measurement.
- Open-channel: radar or submerged ultrasonic? — for sewers and partially-full pipes Telog uses the area-velocity method. The Raven-Eye 2 is non-contact radar (±0.5% velocity) — nothing touches the stream, so no fouling and no confined-space entry; the Beluga is submerged ultrasonic (±1%) that works even when the pipe surcharges, with integrated level and shallow-flow capability. Radar when you can see the surface and want the highest velocity accuracy; ultrasonic when it surcharges or radar can’t see in.
- Capture transients when they matter — for surge and water-hammer analysis specify the high-speed impulse variants — HPR-32iA, PR-32iA and the Ru-32iMA — which capture fast pressure transients a standard recorder would miss. Routine pressure logging and transient capture are different jobs — pick the impulse build when surge is the question.
- Plan the data path — cloud, SCADA, or both — Telog devices report to the Telog RM cloud (built on Esri ArcGIS) over their cellular link; the line-powered RTUs and gateways can also export to your SCADA over Modbus RTU, 4–20 mA or SDI-12, while the battery cellular recorders deliver through the cloud. Decide the destination — and confirm the outputs your specific device carries — up front.
To size & select the right Telog PR-32A:
Use the input form to tell us what you need to measure and where, how the site is powered (battery, solar or AC), and how you want the data (the Telog RM cloud, your SCADA, or both) — and we’ll spec the recorder, RTU, sensor and outputs for your monitoring program.
