Product Introduction

Reliable and Economical Wet Dial Stainless Steel Water Meter for General Purpose Metering
This Wet Dial Stainless Steel Rotary Multi Jet Water Meter combines the durability of a stainless steel body with the simplicity and cost-effectiveness of wet dial technology. Designed for applications where budget considerations are paramount yet quality cannot be compromised, this meter offers accurate measurement of clean water in residential, commercial, and light industrial settings. The wet dial register operates with direct gear drive in water, ensuring reliable performance without the need for magnetic coupling. Crafted from 304 or 316 stainless steel, the meter resists corrosion and mechanical stress, providing long service life even in challenging environments. Available in sizes DN15 to DN65 with threaded connections (BSP or NPT), it is the ideal choice for volume users, housing projects, and general water distribution networks.
Distinctive Characteristics

- Stainless Steel Robustness – Body manufactured from premium stainless steel (304/316 options) to withstand rust, corrosion, and physical impact. Ensures decades of trouble-free operation in both indoor and outdoor installations.
- Wet Dial Register Design – Simple and proven direct-drive mechanism where the counter is immersed in water. Eliminates magnetic coupling costs, reduces component count, and enhances reliability in clean water applications.
- Multi-Jet Measuring Principle – Water enters through multiple tangential ports, creating a balanced flow that drives the rotor. Self-cleaning action prevents sediment buildup and maintains accuracy over time.
- Rotary Piston Technology – The rotor spins freely on a hardened stainless steel shaft, providing smooth and consistent measurement across the entire flow range.
- Threaded End Connections – Precision-cut threads (BSP or NPT) ensure easy, leak-free installation with standard pipe fittings. Available in various lengths to suit different piping configurations.
- Transparent Register Cover – Impact-resistant plastic cover allows clear viewing of the 8-digit roller counter. The wet environment keeps the lens free from internal fogging, though occasional cleaning may be needed for optimal readability.
- Wide Operating Range – Suitable for cold water up to 50°C and hot water up to 90°C, making it versatile for most residential and commercial systems.
- Low Pressure Drop – The multi-jet design minimizes energy loss, ensuring efficient system operation.
- Customizable Options – Pulse output modules can be added for remote reading; OEM branding and custom packaging available for bulk orders.

Typical Applications

This wet dial meter is perfectly suited for environments where initial cost is a key factor and water quality is consistently clean:
- Residential Complexes – Apartments, housing societies, individual homes – reliable and affordable billing.
- Commercial Buildings – Offices, schools, hospitals – general water consumption monitoring.
- Industrial Facilities – Factories, warehouses, cooling towers – non-critical process water measurement.
- Irrigation Systems – Farms, greenhouses, agricultural water supply.
- Temporary Installations – Construction sites, event venues – cost-effective temporary metering.
- Developing Regions – Affordable solution for water utilities in emerging markets.
- Secondary Networks – Sub-metering in large residential or commercial developments.
Wet Dial Technology Explained
1. How It Works:
In a wet dial meter, the entire counting mechanism is immersed in the water being measured. The rotor drives a series of gears directly connected to the register. Water acts as a lubricant, reducing friction and wear.
2. Advantages of Wet Dial Design:
- Simplicity – Fewer components (no magnetic coupling) mean lower manufacturing cost and fewer potential failure points.
- Reliability – Proven technology with decades of field experience in clean water applications.
- Cost-Effective – Ideal for large projects where budget constraints are tight.
- No Magnetic Interference – Not affected by external magnetic fields, making it tamper-resistant in some respects.
- Easy Maintenance – The register can be replaced without special tools if needed.
3. Comparison with Dry Dial:
| Aspect | Wet Dial (This Product) | Dry Dial |
|---|---|---|
| Register Isolation | Immersed in water | Hermetically sealed |
| Magnetic Drive | No – direct gear drive | Yes – magnetic coupling |
| Cost | Lower | Higher |
| Fogging | Not applicable (under water) | Anti-fog coating required |
| Suitable Water Quality | Clean, sediment-free | Suitable for various qualities |
| Maintenance | Minimal; periodic cleaning if water dirty | Sealed – no cleaning needed |
Installation Instructions
Before You Begin:
Ensure pipeline is clean and free of debris, sand, or weld spatter.
Verify that the meter's thread size and type match your pipe fittings.
Allow sufficient space for reading and future maintenance.
Installation Steps:
Apply PTFE tape or pipe sealant to the male threads of the pipe ends.
Screw the meter onto the pipe hand-tight, ensuring the flow direction arrow aligns with actual flow.
Tighten with a suitable wrench – do not overtighten, which could damage threads or the meter body.
For horizontal pipelines, position the register face up. For vertical lines, flow must be upward.
Slowly open valves to pressurize the system and check for leaks.
If a strainer is present upstream, clean it regularly as per the manufacturer's recommendation.
Notes:
Avoid installing in locations subject to freezing temperatures.
Protect from excessive vibration or mechanical shock.
The register can be rotated 360° for best viewing angle.

Maintenance and Care
- Periodic Cleaning – In areas with high sediment, the meter may require internal cleaning. Disassemble carefully (consult manual) and rinse components with clean water.
- Register Replacement – If the counter becomes unreadable due to wear, replacement registers are available as spare parts.
- Strainer Maintenance – If an external strainer is installed, clean it monthly or as needed.
- No Lubrication Required – Water acts as a natural lubricant for the moving parts.
- Long-Term Storage – If the meter is not used immediately, store it in a dry, protected area; fill with water before installation to prevent seal drying.

Frequently Asked Questions
Q1: What is the main advantage of a wet dial meter?
A: Wet dial meters are simpler in construction and more economical than dry dial types. They have fewer parts, which reduces cost and potential failure points, making them ideal for large-scale projects with clean water.
Q2: Can the wet dial meter be used for hot water?
A: Yes, our standard model is rated for hot water up to 90°C. For higher temperatures, please consult our sales team.
Q3: How does the register remain readable if it's immersed in water?
A: The transparent cover allows direct viewing of the digits through the water. The water actually helps keep the lens clean and free from internal condensation.
Q4: What water quality is required?
A: The meter is designed for clean, non-aggressive water. Suspended solids or fibrous materials can clog the mechanism; a strainer is recommended upstream.
Q5: Can I get a pulse output with this wet dial meter?
A: Yes, we offer an optional pulse output module that can be installed externally or integrated during manufacturing. Please specify your requirement.
Q6: What is the minimum order quantity?
