Telog — Remote Telemetry & Field Recorders

Telog is Badger Meter’s infrastructure-telemetry line — battery-powered, cell-tower-based, and solar-ready standalone recorders and cellular RTUs that monitor pressure, level, flow, and rainfall across a water or wastewater network. It watches the system itself (pressure zones, hydrants, pump stations, sewers), logging to local memory first and optionally streaming to the Telog RM cloud.

Pressure — the HPR-32A hydrant recorder and PR-32A pipeline recorder; fast pressure transients and water hammer — the high-speed impulse HPR-32iA / PR-32iA; rainfall — the RG-32A tipping-bucket rain gauge; and open-channel level, velocity, and flow — the Raven-Eye 2 radar-Doppler (±0.5% velocity) and Beluga submerged-ultrasonic (±1%) sensors. The Ru-35 and RS-45 multichannel RTUs add flow, pressure, and water-quality inputs over RS-485, analog, and SDI-12; the battery-cellular Ru-32mA/iMA take I2C pressure, 4–20 mA, 0–5 V, pulse, and encoded-register inputs only.

For sewers, channels, and partially-full pipes — where a closed-pipe meter won’t work — Telog measures by the area-velocity method (level × velocity, no flume or weir needed), with two sensor choices. The Raven-Eye 2 is a non-contact radar sensor that mounts above the flow: nothing touches the stream, so there is no fouling and no confined-space entry to service it, and it reads velocity to ±0.5% (flow to ±5%) — ideal for CSO/SSO monitoring, inflow-and-infiltration analysis, and custody-transfer billing. The Beluga A/V is a submerged ultrasonic (Doppler) sensor that mounts in the channel and works in both partially-full and fully surcharged pipes, using real-time spectral analysis of the velocity profile (±1%) — the choice when the pipe surcharges or a radar cannot see the surface. Both feed the IFQ Monitor head-end (RS-485 in, dual 4–20 mA plus optional Modbus out, with onboard logging) or a Telog Ru-35 / RS-45 RTU for cloud or SCADA delivery.

The battery recorders (HPR-32A, PR-32A, RG-32A) store data internally for many months and are the tool for surveys and temporary studies — fire-flow tests, hydraulic-model calibration, pressure-zone surveys — where you collect on a schedule. The cellular RTUs (Ru-32mA/iMA, Ru-35, RS-45) transmit to the Telog RM cloud for permanent, real-time remote monitoring and alarming. Choose a recorder for portable or temporary work; an RTU for fixed sites you need to watch continuously.

The Ru-35 is the IP68 submersible RTU built for underground vaults and sewers; paired with a Beluga submerged-ultrasonic or Raven-Eye 2 radar area/velocity sensor it captures CSO/SSO overflow events and inflow-and-infiltration data for regulatory compliance and collection-network model calibration. For continuous-duty wastewater monitoring on external AC or solar power, the RS-45 carries up to two sensors per RTU.

No. Every device logs to local memory first and runs standalone indefinitely — a site keeps recording with no power and no signal. The battery recorders need no external power and last many months between collections; the RS-45 is solar-ready — it runs on an external DC feed (an AC adapter, or a customer-supplied solar panel and battery) for continuous duty, with its internal battery as UPS backup, and for an off-grid site Prater Technical can spec a matching SunWize solar power system to feed it. The cellular models transmit on a defined schedule and buffer their data when coverage drops, so nothing is lost.

Telog RM is the cloud Remote Monitoring platform — a GIS-centric (Esri ArcGIS) web and mobile portal with the Telog Historian archive, alarms, and reporting for capital planning, capacity, and regulatory compliance. It is optional: the recorders and RTUs work standalone and can export to your own SCADA over Modbus RTU, 4–20 mA, or SDI-12. Use the cloud, your SCADA, or both.

The Ru-35, RS-45, and recorder lines export to SCADA over Modbus RTU, 4–20 mA, and SDI-12 (the battery-cellular Ru-32mA/iMA report through Telog RM instead), and the Ru-35 adds RS-232/RS-485 and I2C sensor interfaces. For GIS, Telog RM is built on Esri ArcGIS, with an ArcGIS connector and a Historian API to push data into your existing systems.

Telog is an engineered system configured to your monitoring program, so it is quote-only — there is no webstore pricing. Tell Prater Technical what you need to measure, where, how it should be powered (internal battery, or an external AC or solar feed), and how you want the data (cloud, SCADA, or both); we spec the recorder, RTU, sensor, and power — including a matching SunWize solar power system for off-grid sites — configure the outputs, and ship from our Brooklyn facility. Programming and commissioning assistance are available from Prater as an optional, quoted service.
