Is a counter guarantee?
Many buyers rightly ask whether their investment, however small, is guaranteed. Well, NO, only the manufacturer's warranty is valid, and very few anomalies occur , since meters are factory-checked for accuracy at high, low and medium flow rates. What's more, most of them comply with AWWA (American Water Works Association) standards.
If you install your meter on a drinkingwater line, taking into account all the manufacturer's specifications ( e.g. maximum pressure, flow rate, temperature of cold or hotwater ), you 'll have no problem whatsoever with your meter lasting for ages. If you needa meter for any other application (e.g. immersion, wet environments, unsafe"cloudy" water, food or chemical liquids, etc.), be aware that each process is different, and that whether by the addition ofa strainer,a drain valve after use or otherwise, a meter model exists. For these specific cases, talk to one of our technicians , who will be able to guide you and meet your needs.
What types of liquids are your meters compatible with?
Our basic meters are designed for drinking water only. However, we have several types of meter for other liquids. Here are a few examples:
- Waste water meters ( Endress&Hauser)
- Maple water meters (Badger Meter)
- Oil meters (Aquametro)
- Milk meters (Badger Meter)
- Chemical meters ( Please contact us for more information)
- Diesel Meter (Aquametro)
- Glycol meters (Please contact us for more information)
For all other liquids (except natural gas ), we invite you to contact our specialists.
For the right meter and a quick quote.
You need to know the type of liquid, its viscosity, maximum temperature and maximum flow rate.
What do diameters with 2 ratios mean?
The first ratio refers to the internal dimension of the meter mouths. Although this terminology is still used today, it should be removed from the vocabulary of water meters and should never be considered.
The 2nd report indicates the size of the meter 's inlet and outlet diameters. This data must be taken into account when connecting the meter to the pipework.
Example: 5/8 x 1/2, 5/8 x 3/4, 3/4 x 3/4
So,
- A (5/8 x) 1/2 meter is a low-flow water meter (maximum 20 gpm) for installation in residential homes with 1/2-inch piping.
- A (5/8 x) 3/4 meter is a low-flow water meter (maximum 20 gpm ) for residential installation with 3/4-inch piping.
- A (3/4 x) 3/4 meter is a high flow (maximum 35 gpm ) water meter for installation in commercial or apartment buildings (residential) with 3/4 inch piping.
Can all meters be installed in any position?
First of all, the meter must be installed in the direction of flow indicated by a raised arrow on the casing.
For optimum performance , the meter should be positioned horizontally, with the register facing upwards.
If this makes the register impossible to read, it can be tilted by 45 degrees. Never install a meter with the register facing the ground.
Where it is not possible to install the meter horizontally, the vertical position may be chosen , but with the proviso that service life and accuracy at low flow rates may be affected. It is important to follow the manufacturer's instructions to ensure the best possible data accuracy.
- Propeller, single-jet , multi-jet and turbine meters must be installed horizontally (LC, LR models).
- Volumetric meters (Badger models M25, M55, M120, M170) can be installed horizontally or vertically.
What to choose between water meter models LR, LC or M25, M35, M55, M120, etc.?
If you only need a meter for reading directly on the register, installed in a horizontal position, you can opt for model LR in diameters ¾ to 1½ inch.
For diameters of 2 inches and over, the LC model is ideal.
If you need to install the meter in a vertical position, or if your field of activity or your installations require that the meter be NSF61 marked or conform to certain AWWA standards, Badger brand models (M25, M35, M55, M120, M170, etc.) will be suitable for diameters from ¾ to 4 inches.
If the liquid to be measured is other than water , or if you require a remote reading, a pulsed signal or another specific option, we invite you to contactone of our representatives to ensure you make the best choice for your installation.
What is the minimum information required to determine the most appropriate meter type for an installation?
- What type of liquid: drinking water, maple water, waste water, oil, diesel, etc.?
- Is it cold or hot water?
- If hot water: what is the maximum temperature?
- What is the pipe diameter?
- Is it for horizontal or vertical installation?
- What is the maximum operating pressure?
- What type of building will the meter be installed in?
- Is it for a reading taken directly on the meter or a reading at another location (e.g. outside the building)?
- Do you need the meter to emit a pulsed signal or have a 4-20mA output?
- Will the meter be connected to a PLC?
If I install a direct-reading meter, can I modify it later to be able to read it remotely?
Yes, it is possible to do this on certain types of meter by replacing the meter register and installing a remote reading unit, usually connected by a wire. However, some types of meter cannot be modified, in which case the entire meter will have to be replaced. It is therefore preferable to plan for this at the time of the original installation.
Can a water meter be damaged by frost in winter?
Yes, the meter could become unusable if left in an unheated room during the winter, if water is not circulating and if the temperature drops below freezing. If it is not used during the winter, it should be completely emptied of all liquid to prevent breakage.
What different signals are available for each counter?
Pulsed signal
In the field of water meters, a pulsed signal is explained by a +1 pulse for a given quantity. It is a mechanical contact signal requiring no external power supply. The pulsed signal is a dry contact, i.e. no polarity between positive and negative.
4-20mA signal
The 4-20mA signal is a current loop also used to communicate with meters or flowmeters, consisting of circulating a current whose intensity is the transmitted signal. It is a data range similar to 0-100%, with 4 mA representing the minimum of the range, and 20 mA representing the maximum of the range, with a linear relationship between the signal to be transmitted and the current intensity. Thus, a current of 8 mA corresponds to 25% of the range.
Transistorized signal
The transistorized signal requires a direct-current voltage supply (VDC). It provides greater counter accuracy , since the pulse is delivered more quickly than a dry contact. It uses photocell technology to transmit the pulse.

Is a home concealing a water leak and what could the cost be?
A rise in water consumption costs could indeed mean the presence of a leak. To be sure, simply read the consumption figures in the evening, then read them again the following morning, taking care to turn off all water-using appliances and taps during this period. The difference between these two readings would indicate how much water had leaked during that period. The difference between these two readings would indicate the amount of water that leaked during this period.
This exercise can be used to determine the seriousness of the situation. For example, it is possible to calculate a loss over a period ofone year by performing the calculation below.
| Qt | quantity of water measured (m3) |
| P | duration of study period (h) |
24 X 360 X(Qt/P) = annual loss (m3 )
For example, we take a water meter reading in the evening at 10 pm. The water meter reads 1452 m3 and another water meter reading at 8 a.m. the next morning reads 1468 m3.
The difference between the two readings is 16 m3 for a 10-hour period.
| Qt | 16 m3 |
| P | 10 h |
So, 24 X 360 X (16/10) = annual loss of 13824 m3
Finally, by multiplying the result of the annual loss calculation (13824 m3) by the unit cost found in the bill issued by the city ($/m3), we obtain the cost of the water leak to the homeowner.
Where is it possible to encounter a water leak in a residence?
Whena leak comes from the toilet, it 's easier to check and repair if necessary.
In the evening, put a dye in the toilet tank. Take an initial reading of the water meter. Do not use the toilet until the next reading the following morning. If there is a discrepancy between the two readings and the water in the tank is paler than the previous day, or if the water in the bowl has become coloured overnight, the toilet is leaking.
ATTENTION: In some cases, the flush lever may get stuck when activated due to a lack of space, preventing the water from flowing out of the tank into the bowl. Since the cistern must be filled until the water level has pushed the float to the desired height, the mechanism will not stop and the water will continue to flow, trying to fill the cistern but to no avail.
Note that a water leak may originate from a water heater, a faucet nozzle, a poor connection between a garden hose and a shower head, or a thoric seal or sealing washer on a faucet.
The MAMH is asking me to install meters in the ICI (institutions, businesses, industries) in my municipality, why do I have to install them in my institutions if I can 't bill these establishments?
You must install a meter in the institutions in order to know your total consumption for ICI and to identify potential leaks.
Thanks to this data, you' ll also be able to get an approximate idea of your residential consumption by subtracting the quantity from that produced at the drinking water plant.
Example:
- Industry – 1000 m3/day
- Commerce – 500 m3/day
- Institution – 250 m3/day
Your ICI consume 1750m3/day.
- Plant production - 2500 m3/day
- Estimated network leakage - 25 m3/day
We can therefore deduce that our residential sector consumes 725 m3/day (2500-25-1750 = 725). This data will help us to determine our consumption per person per day.
