Kranti is a very well-known and established Indian brand for water meters, widely used in residential, commercial, and industrial applications. When you say 'Kranti water meter screwed, ' you're referring to a common type of end connection for these meters, particularly for smaller sizes.
Here's a breakdown of Kranti screwed-end water meters:
1. Type of Meter:
Kranti primarily manufactures mechanical water meters, which measure flow using a turbine or impeller that rotates with the water flow. For screwed-end connections, these are typically:
Multi-Jet Water Meters: These are very common for domestic and smaller commercial applications. They have multiple jets (inlets) that direct water onto the impeller, distributing the force evenly and reducing wear, leading to better accuracy and longer life, especially at lower flow rates.
Dry Dial: The counting mechanism is sealed from the water, preventing condensation or dirt from affecting readability.
Magnetic Transmission: The movement of the impeller is transmitted to the register via a magnetic coupling, which isolates the register from the wet part and prevents leaks.
Single-Jet Water Meters: Less common than multi-jet for modern domestic applications, but Kranti might offer them for specific needs. They are simpler in design.
2. Screwed End Connection:
Sizes: Screwed-end water meters from Kranti are typically available in smaller sizes, commonly ranging from 15mm (1/2 inch) to 50mm (2 inches). Larger meters usually come with flanged connections.
Threads: The screwed ends will have standard pipe threads, such as:
BSP (British Standard Pipe): This is very common in India (either BSPT - Taper or BSPP - Parallel).
NPT (National Pipe Taper): Less common in India for water meters, but possible.
Material of Connection: For screwed-end meters, the body and hence the end connections are usually made of Brass or sometimes Bronze for durability and corrosion resistance.
3. Key Features of Kranti Screwed Water Meters:
Standards Compliance: Kranti water meters (including screwed types) typically conform to Indian and international standards such as IS 779:1994 and ISO 4064 (Class B). Class B is a common accuracy class for domestic and commercial meters.
Magnetic Drive: Ensures a leak-proof and hermetically sealed register, preventing water from reaching the counting mechanism and fogging the display.
Multi-Jet Design (for relevant models): Provides high accuracy, sensitive metrology, and low-pressure loss.
Robust Construction: Often features a brass body or cast iron body with a brass chamber, ensuring longevity and reliability.
Easy Readability: Analog cyclometer type register with clear digits (often 7 rollers and 2 pointers) for straightforward reading.
Durability: Designed for long-term use in residential and commercial settings.
Temperature Suitability: Typically designed for cold water applications up to 45°C or 50°C. Kranti also offers hot water meters (up to 90°C), which may also have screwed ends in smaller sizes.
Working Pressure: Usually rated for a maximum working pressure of 10 bar or 16 bar.
ISI Marked: Many Kranti meters are ISI marked, signifying compliance with Indian quality standards.
4. Applications:
Kranti screwed-end water meters are primarily used for:
Residential Homes: Measuring water consumption for billing.
Apartment Buildings: Individual flat metering.
Small Commercial Establishments: Shops, offices, small businesses.
Small Industrial Units: Where precise measurement of water intake is required for process or general use.
