Multical - Model 21 - Residential Water Meter
From Smart Water Meters
MULTICAL® 21/ flowIQ® 210X is a static water meter with integrated radio transmission that allows for safe and rapid capture of remotely read data. It is the result of Kamstrup's 25 years of experience within the development and production of static ultrasonic meters. The sophisticated ultrasonic measurement technique makes MULTICAL® 21/ flowIQ® 210X an excellent choice for measuring household water consumption. Not only does it guarantee pinpoint accuracy and longevity, it also helps utilities ensure that the water they provide is of right quality. All of these features are of great benefit to utilities, consumers and the environment.

MULTICAL 21 is an integral and hermetically closed static water meter intended for the registration of cold and hot water consumption. The water meter measures water with temperatures from 0.1°C to 70°C. The water meter uses the ultrasonic principle and has been constructed on the basis of Kamstrup's experience since 1991 with the development and production of static ultrasonic meters.Longevity
One of the water meter's many advantages is the maintained precision through a long life in service. The water meter has no moving parts, which entails high immunity towards particles and thereby longevity. The meter's low starting flow from 2 l/h secures accurate measurements even at low water flows corresponding to a dripping water tap.
MULTICAL 21 is constructed as a vacuum chamber of molded composite material. In that way the electronics are fully protected against penetration of water. This means that the water meter can be placed in e.g. bathrooms and in meter pits, which are frequently filled with water. The meter is easy to install in all operating environments, both horizontally and vertically independent of piping and installation conditions.Ultrasonic
The volume is measured using the bidirectional long-term stable ultrasonic technique. Flow measurement with ultrasound guarantees a very high accuracy. There are no moving parts in the sensor,
which means no wear, and at the same time it makes MULTICAL 21 resistant to impurities in the water. Only what is consumed is being measured – The ultrasonic principle effectively prevents after flow. The accumulated water consumption is displayed in cubic metres (m³) with five digits and up to three decimals, i.e. the resolution has been extended to 1 litre only.
MULTICAL 21 has a built-in sensitive leak monitoring, which detects as low as 0.1% of Q3, meaning that water waste is detected very quickly. The meter continuously measures both water and ambient temperature and stores both minimum and maximum daily temperatures.
The water meter has an optical eye, making it possible to read consumption data and info codes stored in the data logger. Using a serial PC connection, allows the optical eye also allowed to configure the water meter. All data is stored daily in the meter's memory in 460 days and monthly data are stored for the last 36 months. The water meter is powered by an internal lithium battery that provides up to 16 years of life.
The high accuracy and long life combined with built-in radio communications reduces the operating costs for the water company continuously, and contingencies by any possible leakage will be minimized.
MULTICAL 21 is approved for drinking water in several countries. Both flow part and meter housing are made of the synthetic material, PPS, which does not contain lead and other heavy metals. This means low environmental impact and high recyclability of materials when the meter is taken out of service.
