Flow Meters may sound technical, but the idea is simple: they measure how much liquid or gas is moving through a system. In Singapore, where industries are required to operate efficiently and comply with strict regulations, Flow Meters are critical tools.
Imagine running a water treatment plant, an oil depot, or even a factory air system. Without a Flow Meter, you wouldn’t know exactly how much water, oil, or air is being used or wasted. This could mean higher costs, safety risks, and even non-compliance with local regulations.
That’s why businesses in Singapore from municipal utilities to chemical plants depend on flow meters for:
Accuracy: Knowing the exact flow rate in real time.
Efficiency: Reducing energy and material waste.
Compliance: Meeting PUB (Public Utilities Board) and NEA (National Environment Agency) standards.
Safety: Detecting leaks, overflows, or abnormal conditions.
Now let’s look at the types of Flow Meters available in Singapore and where they fit best.
Types of Flow Meters in Singapore
At Ansac Technology Pte Ltd, we provide a wide range of flow meters that cater to different industries and applications. Here are the most common types explained in simple terms:
1. Ultrasonic Flow Meters
How it works: Sends ultrasonic sound waves through the fluid and measures how fast they travel.
Why it matters: No moving parts = long lifespan and low maintenance.
Common uses in Singapore: Water supply systems, building HVAC, and chemical dosing plants.
2. Electromagnetic Flow Meters
How it works: Measures conductive liquids by detecting voltage induced as fluid flows through a magnetic field.
Why it matters: Handles dirty, corrosive, or slurry fluids with high accuracy.
Common uses in Singapore: Wastewater treatment, food & beverage, pharmaceutical, and chemical plants.
3. Thermal Mass Flow Meters
How it works: Uses heat sensors to measure the mass of gases directly.
Why it matters: No need for separate temperature or pressure compensation.
Common uses in Singapore: Monitoring compressed air, natural gas pipelines, greenhouse gases, and industrial emissions.
4. Oval Gear Flow Meters
How it works: Two oval gears rotate as fluid passes, measuring volume precisely.
Why it matters: Highly accurate, even with thick or viscous fluids.
Common uses in Singapore: Oil depots, marine fuel measurement, lubricant dispensing, and energy plants.
5. Area Velocity Flow Meters & Level Monitoring
How it works: Measures both water level and velocity in open channels or partially filled pipes.
Why it matters: Perfect for irregular flow environments like drains and stormwater channels.
Common uses in Singapore: Sewage monitoring, stormwater drainage, and irrigation systems.
Comparison Table: Types of Flow Meters in Singapore
Flow Meter Type | Best For | Advantages | Limitations | Example Brand |
Ultrasonic | Clean liquids, water, HVAC | Non-intrusive, low maintenance, long lifespan | Not ideal for dirty or aerated fluids | Badger Meter |
Electromagnetic | Wastewater, food, chemicals | Very accurate, works with dirty/corrosive fluids | Only works with conductive liquids | Badger Meter |
Thermal Mass | Gases (air, natural gas, emissions) | Direct mass flow, no temp/pressure compensation needed | Not suitable for liquids | Sierra Instruments |
Oval Gear | Oils, fuels, lubricants | Very accurate, handles viscous fluids, durable | Moving parts = some maintenance | Macnaught |
Area Velocity & Level | Wastewater, stormwater, open channels | Measures both velocity & level, works in partially filled pipes | Less suited for clean pressurized pipelines | Pulsar |
Why Choose Ansac Technology for Flow Meters in Singapore?

Identify the right Flow Meter based on your fluid type, accuracy needs, and installation environment.
Access international trusted Flow Meter brands like Badger Meter, Sierra Instruments, Macnaught, and Pulsar.
Ensure compliance with Singapore’s strict industry and safety regulations.
Frequently Asked Questions (FAQ)
Q1. What is the difference between a Flow Meter and a Water Meter?
A Water Meter is a specific type of Flow Meter used mainly for billing water usage. A Flow Meter can measure many different fluids: water, oils, gases, or slurries for industrial purposes.
Q2. Can Flow Meters in Singapore be used outdoors?
Yes. Many models (e.g., ultrasonic and electromagnetic) are designed to be weatherproof and suitable for outdoor use, even in Singapore’s humid climate.
Q3. How accurate are Flow Meters in Singapore?
Accuracy varies by type. Electromagnetic and oval gear meters can reach ±0.2–0.5%, while ultrasonic and thermal mass meters are usually around ±1%.
Q4. Do I need different flow meters for liquids and gases?
Yes. For gases, thermal mass Flow Meters are recommended. For liquids, ultrasonic, electromagnetic, or oval gear Flow Meters are more suitable.
Q5. What maintenance is required for Flow Meters in Singapore?
Non-intrusive models (ultrasonic, electromagnetic, thermal mass) need minimal maintenance.
Mechanical models (oval gear) may require occasional cleaning and calibration.
Regular calibration checks are recommended for all types to maintain accuracy.
Q6. Which industries in Singapore use Flow Meters the most?
Industries like oil & gas, water treatment, chemicals, pharmaceuticals, food & beverage, marine, and semiconductor manufacturing rely heavily on Flow Meters.
Q7: Are Flow Meters necessary only in large-scale industries?
Not at all. While industries like oil & gas and water plants use them daily, smaller businesses such as automotive workshops and HVAC contractors also rely on Flow Meters.
Q8. Where can I buy Flow Meters in Singapore?
Ansac Technology Pte Ltd supplies a full range of Flow Meters from trusted brands like Badger Meter, Sierra Instruments, Macnaught, and Pulsar, with expert consultation and after-sales support.
Key Takeaways
Flow meters are essential tools for measuring liquids, gases, and wastewater accurately.
They help industries save costs, comply with regulations, and protect the environment.
Different types of Flow Meters suit different needs from ultrasonic for water to oval gear for oils.
