Quick Answer: Badger water meter blocks and the Recordall Series are common in municipal utility billing infrastructure for small diameter potable water lines. These meter blocks suit residential and commercial service connections from DN15 to DN50. Silver Instruments supplies larger flow meters, pressure transmitters, and paperless recorders for master meter pits, district metered areas, and billing verification in water and wastewater networks.
Municipal water utilities in Southeast Asia and the Middle East often run billing networks with hundreds of small meter blocks. A Badger water meter block includes the meter body, register head, strainer, and pulse output wiring. Repair crews replace the register or the block assembly on site without cutting the main line. This modular approach keeps billing data continuous. We have seen this on customer sites many times in Jakarta and Manila where billing disputes depend on register readings.
Recordall Series meters cover typical service line flows from 0.25 to 50 cubic meters per hour depending on pipe size. A DN15 meter may handle flows as low as 0.03 cubic meters per hour and still register water use. For billing infrastructure, utility staff look at register type, pulse output scaling, and low flow accuracy. Badger meters in this series often use a sealed register with an encoder output. That output feeds an AMR radio or a wired pulse collection panel.
Small water meter blocks serve residential accounts. Bulk transfer stations, pump stations, and reservoir outlets need larger meters with 4-20 mA HART or Modbus outputs. A DN200 electromagnetic flow meter from Silver Instruments measures bidirectional flow and has no moving parts. Municipal engineers often pair a Silver Instruments electromagnetic flow meter with a Badger water meter block on the same supply zone. The small meter block handles billing for individual connections. The electromagnetic meter handles master flow verification and water loss calculations.
Billing records need audit trails. A paperless recorder receives the 4-20 mA signal from a Silver Instruments flow meter and logs totalized volume every hour. The recorder stores data on a USB drive or SD card. Utility operators download the file once per month. In practice, most utility billing teams skip the recorder until a billing dispute appears. Then the stored flow data becomes evidence for the invoice. We have supplied this setup to a water authority in Durban and a district utility in Cebu.
For meter blocks and small commercial billing points, the Recordall Series is a proven choice. For bulk water billing and chemical dosing lines, Silver Instruments offers electromagnetic flow meters, ultrasonic flow meters, oval gear flow meters, Coriolis mass flow meters, vortex flow meters, and thermal mass flow meters. An oval gear flow meter works for viscous water or polymer with liquid viscosity up to 100 cP. A thermal mass flow meter works for air and digester gas from 0 to 500 kg/h in an ATEX Zone 1 area at a wastewater plant. A Coriolis mass flow meter works for chemical dosing where density changes need compensation. We also supply pressure transmitters with PT100 input for pump station monitoring.
Meter pits in the Middle East and Southeast Asia often flood during heavy rain. A water meter block with an IP68 register survives temporary submersion. The pulse cable must be routed through a sealed conduit. Many utilities use a 24 V DC pulse output loop with twisted pair cable. For long cable runs over 100 meters, a 4-20 mA output is more stable. Silver Instruments flow meters include 4-20 mA HART and RS485 Modbus as standard options. The wiring terminals are labeled on the board. No special software is needed to set the pulse scaling.
Procurement teams ask us for price comparisons between water meter blocks and inline flow meters. A DN50 water meter block costs less than a DN50 electromagnetic flow meter. The electromagnetic flow meter gives better accuracy over a wider range and has no rotating parts. For utility billing infrastructure, total cost includes meter body, register, installation fittings, and data integration.

Are Badger Recordall water meters suitable for desalination plant product water?
They are common for potable water distribution and small billing points. For high volume product water transfer at a desalination plant, use an electromagnetic flow meter or ultrasonic flow meter from Silver Instruments with DN100 to DN1200 line size.
What output options do Badger water meter blocks provide for AMR systems?
Many Recordall Series meter blocks have encoder output or dry contact pulse output. The register output can connect to AMR radios, data loggers, or pulse collection panels. If the control room needs a continuous analog signal, a 4-20 mA HART flow meter is easier to integrate.
Can Silver Instruments supply a meter for raw water with high suspended solids?
Yes. An electromagnetic flow meter with a PTFE liner and electrode cleaning works for raw water with suspended solids and conductivity above 800 µS/cm. A water meter block with a strainer may clog in that service. A customer in Vietnam asked us for a DN150 electromagnetic flow meter after a small meter block on a raw water line clogged twice in one month. Most engineers skip the small meter block on raw water lines above DN80 and select a full bore electromagnetic flow meter.
How do I get a quote for a municipal billing meter package?
Send us your pressure (bar), temperature (°C), pipe size (DN), and flow range in cubic meters per hour. Include fluid type and installation location. Our team will reply with model, price, and lead time.
What is the advantage of a paperless recorder in utility billing?
A paperless recorder stores flow total, pressure, and temperature data. Utility billing staff can print or export the data when a customer disputes a bill. The recorder also helps with water loss audits and non revenue water programs.
