Bulk Ultrasonic Water Meter Kenya – Smart Water Monitoring for DN50–DN600
Bulk Ultrasonic Water Meter Kenya solutions are increasingly important for organisations that need accurate measurement of large volumes of water together with reliable monitoring and communication capabilities.
The Dotmobi SH7650 Bulk Ultrasonic Water Meter is designed for water utilities, borehole operators, industries, housing estates, institutions, irrigation schemes, commercial properties and community water projects.
Available in sizes from DN50 to DN600, the meter uses ultrasonic measuring technology without conventional mechanical moving parts in the flow sensor.
Depending on the selected configuration, it can also support RS485, Pulse, LoRaWAN, GPRS and NB-IoT communication, making it suitable for both conventional bulk metering and smart remote water-monitoring applications.
Why Choose a Bulk Ultrasonic Water Meter Kenya Solution?
Traditional mechanical bulk water meters rely on internal moving components to measure water passing through a pipeline.
Over extended operating periods, moving components can be affected by wear, impurities and continuous use.
The SH7650 instead uses ultrasonic measurement technology with no mechanical moving parts in the flow sensor.
This design helps reduce mechanical wear and supports long-term measurement stability.
For organisations handling significant volumes of water, the meter combines bulk-flow measurement with the possibility of electronic communication and remote monitoring.
Key Features of the SH7650 Bulk Ultrasonic Water Meter
1. No Mechanical Moving Measuring Parts
The meter measures water using ultrasonic technology instead of conventional rotating measuring components.
This reduces mechanical wear and supports a long operating life.
2. Wide Measuring Range
The SH7650 is specified with:
Q3/Q1 R250, with R400 available depending on configuration.
The wide measuring range allows the meter to operate across different water-flow conditions.
3. Low-Flow Measurement
The meter is designed to measure relatively low flows even when installed on larger pipelines.
Low-flow sensitivity can be useful when investigating:
- Unexpected water consumption
- Possible leakage
- Night-time consumption
- Distribution losses
- Continuous abnormal flow
4. Class 2 Accuracy
The SH7650 is specified as an Accuracy Class 2 ultrasonic water meter.
Reliable bulk measurement is particularly important where recorded water volumes are used for:
- Water accounting
- Billing
- Distribution monitoring
- Production-versus-consumption analysis
- Water-balance calculations
- Non-revenue-water investigations
- Water project management
Smart Bulk Ultrasonic Water Meter Kenya Communication Options
A major advantage of smart bulk water metering is the ability to transmit meter data electronically rather than relying entirely on manual readings.
Depending on the ordered configuration, the SH7650 supports:
- LoRa / LoRaWAN
- NB-IoT
- GPRS
- RS485
- Pulse output
These communication options make the meter suitable for projects requiring remote meter reading and integration with smart water-management systems.
Dotmobi can also assess integration of meter information into a cloud-based IoT monitoring platform, depending on the selected communication interface and project requirements.
LoRaWAN Data Transfer Unit for Remote Monitoring
The SH7650 system can be supplied with a LoRaWAN Data Transfer Unit (DTU) for remote transmission of water-meter information.
The specified LoRaWAN DTU configuration includes:
- 868 MHz communication frequency
- Class A operating mode
- IP68 protection
- Long-life battery configuration
- Adjustable automatic data reporting
- Burst-pipe alerts
- Leak-detection alerts
Automatic data transmission can reduce the need to physically visit every meter simply to obtain routine consumption readings.
Instead, water-management teams can use remotely transmitted information to monitor consumption and identify conditions requiring further investigation.
Leak and Burst-Pipe Monitoring
Water losses can become costly when a leak or pipe failure remains undetected.
With the appropriate communication configuration, the SH7650 can support alerts associated with:
- Leakage
- Burst pipes
- Abnormal flow conditions
Smart bulk metering can therefore contribute to a wider water-loss and distribution-management strategy.
Reverse-Flow Detection
The SH7650 display provides status information that includes reverse-flow indication.
Reverse-flow monitoring can help system operators identify unusual pipeline conditions and determine whether water is moving in the intended direction.
Meter Status and Alarm Information
The meter is designed to display operating and diagnostic information including:
- Battery voltage
- Sensor failure
- Reverse flow
- Drip or leak indication
- Pipe-not-full indication
- Error and alarm information
- Water temperature
- Time
- Meter address
These diagnostic features provide more operational information than a conventional meter that only displays accumulated water consumption.
IP68 Bulk Ultrasonic Water Meter Kenya Protection
Bulk water meters may be installed outdoors or in meter chambers where exposure to moisture can occur.
The SH7650 is specified with an IP68 protection rating, making it suitable for demanding water-meter installations when correctly installed.
The associated LoRaWAN DTU is also specified with IP68 protection.
Horizontal or Vertical Installation
The SH7650 supports installation in:
- Horizontal pipelines
- Vertical pipelines
This provides flexibility when designing a new metering installation or upgrading an existing water system.
Correct sizing, pipeline arrangement and installation conditions should still be reviewed before installation.
Available Meter Sizes – DN50 to DN600
The SH7650 range covers bulk water applications from DN50 to DN600.

Where Can a Bulk Ultrasonic Water Meter Kenya System Be Used?
The SH7650 is suitable for several bulk-water applications.
Water Utilities and Distribution Networks
Water utilities can install bulk meters at strategic points within a distribution system to measure water supplied into different zones.
Comparing upstream and downstream measurements can assist with distribution monitoring and water-loss investigations.
Boreholes and Community Water Projects
Borehole operators and community projects can monitor the amount of water pumped into storage tanks or supplied into distribution networks.
Apartments and Gated Communities
A bulk ultrasonic meter can be installed as a master water meter at the inlet of an apartment complex or gated estate.
Management can then compare the master-meter reading with consumption recorded by individual consumer meters.
Factories and Industrial Facilities
Industrial facilities can monitor water entering an entire plant or specific production areas.
Schools, Hospitals and Institutions
Large institutions can use bulk water meters to improve consumption accountability and investigate unexpected increases in water use.
Irrigation and Agricultural Projects
The meters can be used to monitor significant water flows in irrigation and agricultural distribution systems.
Hotels and Commercial Properties
Hotels, malls, office developments and other commercial properties can monitor overall consumption and investigate unusual usage patterns.
Bulk Metering and Non-Revenue Water Management
A smart bulk water meter can provide an important measurement point within a water-distribution network.
For example, an operator can compare:
Water entering a distribution zone
with
Water recorded by downstream consumer meters
An unexplained difference may indicate the need to investigate:
- Leakage
- Metering inaccuracies
- Unrecorded connections
- Operational losses
- Data-collection problems
Bulk metering can therefore provide useful data for district metering, water balancing and non-revenue-water investigations.
Bulk Ultrasonic Water Meter and Prepaid Water Meter
A bulk ultrasonic water meter normally measures large volumes of water entering or moving through a property, distribution zone, institution or water project.
A prepaid water meter is normally installed closer to the individual consumer and controls consumption according to prepaid credit.
The two technologies can work together.
For example:
1 bulk ultrasonic master meter → several individual prepaid water meters
A property manager can compare the total quantity of water entering a development with the combined consumption recorded by individual users.
Dotmobi also supplies STS Prepaid Water Meters for apartments, institutions, landlords, boreholes and water projects.
Water Metering Standards and Good Practice
Water-meter selection should consider accuracy, flow range, operating conditions, installation requirements and the regulatory requirements applicable to the particular project.
The International Organization of Legal Metrology (OIML) identifies OIML R49 as the international recommendation covering water meters.
More information on OIML measuring-instrument categories is available from the International Organization of Legal Metrology.
Project owners should also confirm applicable Kenyan legal-metrology, water-sector and procurement requirements before commissioning a metering installation.
