How many types of counters are there?

Many people get confused when it comes to understanding how their accountant works. Logical if we take into account that there are different types of meters and each one has different characteristics. We tell you how many types of meters exist and how to choose a water meter based on its specifications.

5 things you should know about the 5 types of counters that are available

It is worth mentioning that the Ministry of Agriculture, Fisheries and Food of the Government of Spain is very attentive to water management and even offers information on its website to guide citizens who want to understand the best way to make optimal use of water.

• A filter must be installed before the meter when the water needs filtering for its use.
• To facilitate maintenance and repair work, it may also be necessary to have a system shut-off valve above the meter.
• Watertight joints must be used between the meter and the pipe with an internal diameter identical to that of the meter.
• Straight runs are required on some systems or stabilizing reels before the meter.
• Lastly, if there is a possibility of air pockets forming in the piping system, the meters should have suction cups to prevent incorrect readings.

Types of counters that exist and characteristics

There are five types of counters that we should know since it is important to understand their key differences. Those we appoint are prepared to temperatures below 50 degrees Celsius.

single jet meters

They work through a single jet of water that acts directly on the turbine, whose speed of rotation depends on the impact of the jet.

When installing them, it is done in a horizontal position and they are the type of counters most used in homes. They are very rarely seen in irrigation.

When the caliber is less than 20 millimeters in this type of meter, it is not necessary for there to be straight sections above the meter.

Multi-jet meters

In this type of meters, the water also acts on the turbine, but after passing through different and numerous holes. They are highly recommended mainly because their operation reduces the probability of errors and they are more durable. They are also installed in a horizontal position, but the multi jet meters do not need straight sections pipe above the counter.

Woltmann type meters

The Woltmann counters They have a very particular way of working. The system is based on a propeller that rotates in a perpendicular plane to the direction that the water follows.

Within the Woltmann counters there are three types depending on the rotating axis of the turbine itself: vertical, horizontal or elbow. This type of water meter is the one that we can see the most in plantations and crops due to the wide range of diameters that it offers for its installation, which is between 50 and 300 millimeters of nominal diameter.

These irrigation meters do require a distance of straight sections before the meter and, to prevent solids from blocking the helix, it is recommended install a water filter above the meter.

tangential counters

In the operating system of tangential counters Only one part of the turbine is the one that receives the impact of the water flow, and its axis of rotation is perpendicular. They require the existence of straight sections above the meter.

proportional counters

These types of counters they have two parallel circuits, placing the counter itself in the secondary. Like tangential counters have low accuracy. They must have a filter at the input of the circuit to avoid damage to the counter.
