RV parks and marinas are dynamic places, continually changing. Day-use and overnight renters mix with longer-term tenants greatly enhancing the challenges that are present in any large, outdoor submetering installation.

For marinas and RV parks it is not enough that the AMR equipment be weather-resistant and dependable. Cereniti currently has equipment that has been sitting in concrete pits for a decade or more and it is still working even though it is covered in water and mud for most of the winter. But this is not enough. The AMR infrastructure must also answer the business needs particular to this environment.

Using the data

A great deal of data will be produced and collected by your AMR system, it is important to know that you can get to it and you can get it to work for you. Extracting consumption data once a month for billing purposes might be acceptable in an apartment building but it will not answer the needs of RV park and marina managers. With renters and tenants coming and going at varying intervals, property managers need a system that can provide a near real-time picture of consumption so that each renter might be billed exactly for his or her usage.

Cereniti's DataSense Network answers this need beautifully. Our transmitters can be programmed to transmit updates at almost any interval that you need. This means that billing for day use or for short term stays of only a few days is not only possible, it's simple.


The location of utility meters in RV parks and marinas must fulfill the operators' needs to fit in a large number of vehicles and vessels of different sizes into the property safely, securely, and profitably. That marinas and RV parks will be exposed to the elements is a given, as is their need for technology that will support their business and contribute to it.

At Cereniti, we understand that our technology should make your life easier so we designed our radio transmitters to be effective no matter where you put them.

We have developed high-powered, low frequency transmitters that can be installed almost anywhere. Our transmitters use only FCC-approved frequencies in the 450-470Mhz range; this increases their range and their reliability even if the transmitter on a pier, exposed to the abuse of salt air and weather.

Our outdoor transmitters are IP-68 compliant, which means that they are dust-proof and submersible. Yes, you could drop them in water up to three feet deep and they would still transmit reliably.

Ease of installation

The outstanding radio performance of Cereniti's meters means that they can be installed where ever it is most convenient; that usually means right next to the meter. There is no need to lay cable so that transmitter might be installed in a place with better transmission. There is no need to make alterations or to spend costly time jerry rigging installations that fit the transmitter and not the other way around.

Multiple meters

Developments that submeter water will frequently look for ways to submeter other utilities like gas, electricity, or heating. Installing additional transmitters to cover these utilities can easily be avoided using Cereniti's DataSense. Our transmitters can accept from one to four inputs from a variety of meters. As long as the meters have the same sort of output (pulse or encoded), and are installed in reasonable proximity (up to 12ft), it is usually a simple matter to hook them up to the same transmitter.

Pulse or encoded meters

Pulse and encoded meters each have their own pros and cons. Pulse meters are common and inexpensive, encoded meters are more sophisticated and precise. Apartment and condominium managers should be able to make a decision as to what type of meter is best for their property based on their metering needs, not on the capabilities of their AMR transmitters. No matter what type of meter you choose for your property, we have a transmitter that can work reliably with it.
