ALTAIR V4 CONCENTRIC Cold Water Meter
General Information
OIML R49 and ISO 4064 standards. It has a MID certification and complies with the sanitary standard applying to materials in contact with water.
The ring rotates freely (one full rotation max.), making it readable from all angles. The arrows (4) indicate which way the water is flowing. The holes (5) enable on-site sealing of the meter.
Calibration
ALTAIR V4 CONCENTRIC is MID approved up to R=630.
Pressure Loss
Features
| Filtration | Clog-proof plastic filter located under the measuring chamber. (max. 16 bars). |
| Clogging | Patented fluid collector allowing solid particles to go through the measuring chamber, thus limiting the deterioration of the parts. |
| Static pressure | Nominal pressure: 16 bars max. Test pressure: 32 bars (in accordance with ISO4064 / EN14154 / OIML R49).
Breaking pressure: greater than 55 bars. |
| Resistance to pressure changes | 100,000 rapid rises in pressure from 0 to 16 bars in 0.2 sec. |
| Overflow | Resistance to a flow rate of 2 x Q4 during 2 hours without any damage to the parts. |
| Endurance | Compliant with the MID regulatory tests. Resistance: 100,000 cycles at Q3 and 100 hours at Q4. |
| Non-return valve | Adding a non-return valve in the base is not possible. |
| Fraud resistance | Fraud attempt with a clamp: ➔ The glass/metal register will crush, or the orange pin indicator of the plastic register will disappear. Fraud attempt by opening the sealed ring:➔ Presence of a collar limiting the fraud and visible deterioration of the sealing ring. |
Installation
Position
Horizontal or vertical installation position.
The metered water flow must be free of gas.
Tools
Use the Diehl Metering installation and removal tool. It has two openings for retaining the meter
Liability
If the installation is not carried out in accordance with good workmanship practices, and if the above-mentioned procedures are not followed, the warranty shall be null and void.
Instructions for Use
| Storage | Do not store the meters for more than 3 months. Do not stack the pallets. Do not place loads of more than 80 kg on the meter. |
| Cleaning | Only use soapy water. Solvent fumes may damage the mechanical resistance. |
| Stepping | ALTAIR V4 CONCENTRIC must not be stepped upon. However, with its cover closed, it can withstand the load of a person weighing 80 kg. |
| Drop test | Designed to withstand a fall of 1 m onto a hard floor. In the event of a fall, or if the meter shows traces of impact, we recommend testing it before installation. |
Regulations
ALTAIR V4 CONCENTRIC meter complies with the European and UK directives as indicated on the Declarations of conformity delivered with the product and available on the Diehl Metering website: It also meets the food-grade requirements of ALTAIR V4 CONCENTRIC Cold Water Meter about materials in contact with water.

FAQs
Q: What is the ALTAIR V4 CONCENTRIC Water Meter designed for?
Water use in commercial, industrial, and domestic settings can be precisely measured with the ALTAIR V4 precision cold water meter. Potable (drinking) water systems can use it.
Q: What sizes and flow rates does the V4 support?
There are several pipe diameters and flow ratings for the V4. To ensure compatibility with your system, always read the technical specification label. Depending on the model, flow rate ranges might range from Q1 (lowest flow) to Q4 (highest flow).
Q: How do I read the water consumption?
The meter features a mechanical or digital display (depending on version) showing total water volume in cubic meters (m³). Subdivisions on the dial indicate liters for precise monitoring.
Q: How often should the meter be checked or calibrated?
A qualified technician should carry out the calibration.
Q: Can I install a water meter on any pipe material?
Steer clear of pipes that move or vibrate excessively.
