Product Overview
Woltman turbine water meter, 50mm flanged connection, high flow accuracy, stainless steel components, wide measuring range
The ARAD WST Woltman Silver Turbo 50mm Water Meter is a high-performance bulk flow meter designed for accurate measurement in municipal, agricultural, and industrial water systems. Built using advanced turbine (Woltman) technology, it provides exceptional accuracy across both low and high flow conditions.
Engineered with a unique measuring unit, the meter features only one moving element in contact with water, reducing wear and ensuring long-term reliability. The magnetic coupling system enhances measurement stability while protecting the register from water ingress and environmental conditions.
Constructed with a robust cast iron body with polyester coating and stainless steel internal components, the meter is designed for durability in demanding environments. It is resistant to vibration and humidity, ensuring consistent performance even under harsh operating conditions.
The 50mm flanged connection allows secure installation in pipeline systems, while the IP68-rated sealed register ensures clear readability and protection against water and dust ingress. The wide measuring range enables precise monitoring across varying flow rates.

Frequently Asked Questions
What is the ARAD WSTsb used for?
The ARAD WSTsb Woltman Silver Turbo is designed for bulk water metering in water supply networks, agricultural applications and industrial use. It is suited to larger pipe sizes and higher flow applications where accurate water measurement is required.
What is the maximum working pressure?
The standard maximum working pressure is 16 bar. A 25 bar version is available upon request.
What is the maximum liquid temperature?
The maximum liquid temperature is 60°C.
What is the body made from?
The standard body is cast iron with a polyester coating. A bronze body is also available as an option for AWWA standard applications.
Can the WSTsb be installed vertically?
Yes. The WSTsb can be installed in any position. For non-horizontal installations, the flow direction must be upwards.
Does the WSTsb need straight pipe before and after the meter?
Yes. The installation requirement is U5 / D3, meaning 5 pipe diameters upstream and 3 pipe diameters downstream.
Does the meter need to stay full of water?
Yes. The meter should remain full of water while operating. The pipeline should also be thoroughly flushed before the meter is installed.
What is the register rating?
The WSTsb register is rated IP68, making it suitable for demanding meter pit and outdoor environments.
Is the WSTsb suitable for irrigation?
Yes. The WSTsb is suitable for agricultural water metering and irrigation applications, especially where higher flow rates are required.
What is the accuracy of the WSTsb?
The WSTsb has an accuracy of ±2% between Q4 and Q2 and ±5% between Q2 and Q1.
What standards does the WSTsb comply with?
The WSTsb complies with MID 2014/32/EU, based on OIML R49:2013, EN 14154 and ISO 4064:2014. It also lists WRAS and AWQC standards. Also, approved for Department of WA Water.
