Econo Turbine Flow Meter Prices: Cost-Effective Liquids Metering Solutions
Quick Answer: Econo turbine flow meters from Silver Instruments measure clean water, diesel, palm oil, solvents, and similar liquids at a lower installed cost than Coriolis or electromagnetic meters. Prices start around USD 180 for DN15 and go up to about USD 920 for DN100, depending on material, output, and display options. Send us your pressure (bar), temperature (°C), pipe size (DN), and flow range for a fixed quotation.
What You Pay for an Econo Turbine Flow Meter
The Econo TF series covers DN15 to DN200 for liquid flow measurement. Most buyers request price before anything else. In practice, the cost of a turbine flow meter changes with line size, body material, bearing type, electronics, and hazardous area requirements.
Here is the thing. A plain DN25 turbine meter with pulse output costs around USD 210. The same DN25 meter with a digital display and 4-20 mA HART output often sells between USD 350 and USD 420. The difference comes from the transmitter board, display window, and calibration steps.
Silver Automation Instruments ships these meters to Malaysia, Vietnam, Nigeria, Saudi Arabia, Australia, Mexico, and other industrial markets. Common sectors include water and wastewater, diesel fuel transfer, chemical batching, palm oil processing, food and beverage, and marine fuel measurement.
Price Range by Line Size
| Meter Size | Body Material | Typical Price Range | Common Application |
|---|---|---|---|
| DN15 | SS304 | USD 180 to 320 | Dosing skids and pilot water lines |
| DN25 | SS304 | USD 210 to 380 | Diesel fuel transfer and chemical batching |
| DN40 | SS304 | USD 240 to 430 | Lube oil and boiler feedwater |
| DN50 | SS304 or SS316 | USD 320 to 520 | Palm oil transfer and chilled water |
| DN80 | SS304 or SS316 | USD 420 to 700 | Terminal loading and cooling loops |
| DN100 | SS304 or SS316 | USD 580 to 920 | Bulk water lines and solvent distribution |
These prices are for standard meters without Ex protection. ATEX Zone 1 protection normally adds 25 to 40 percent.
What Drives the Econo Turbine Flow Meter Price
Size is the first cost driver. Larger meters use more stainless steel and larger rotor assemblies.
Material selection changes price quickly. SS304 suits clean water and diesel. SS316 is the right choice for seawater, brine, weak acids, and food contact lines. SS316 bodies add 15 to 25 percent over SS304 in most sizes.
Bearing material affects service life. Tungsten carbide bearings work well in water and light chemicals. Sapphire bearings handle low lubrication liquids such as gasoline and some solvents. The price difference is small, but the operational risk is large if you pick the wrong bearing.
Electronics form the second cost block. A pulse output signal is enough for many PLC and batching systems. A local display with 4-20 mA HART or RS485 Modbus adds cost because operators need the totalized flow at the meter. Display versions use 24 V DC loop power.
Calibration also matters. Every Silver Instruments Econo meter ships with a 5 point water calibration certificate. Specific calibration on diesel or glycol costs USD 50 to 120 and adds 2 to 3 working days to the order.
Technical Limits and Selection Tips
Econo turbine meters handle clean liquids between 1 cP and 50 cP. A DN50 meter covers about 4 to 40 m3/h on water. Standard temperature range is -20 to 120 degrees Celsius. Standard pressure rating is 40 bar with higher ratings on request.
Do not use a t

Straight pipe length matters. Use 10D upstream and 5D downstream for stable flow profiles. This practice preserves meter accuracy and repeatability.
Accuracy is 1.0 percent of reading under standard water calibration. Dedicated liquid calibration can improve accuracy to 0.5 percent of reading. Repeatability is better than 0.2 percent in most installations. Standard housing is IP65. Use IP67 for flooded pits and outdoor washdown areas.
Country and Industry Examples
A palm oil mill in Malaysia ordered eight DN80 Econo turbine meters for transfer lines. SS316 bodies and pulse outputs kept the full order under USD 5,000 including air freight.
A paint manufacturer in Vietnam asked us last year about solvent batching. We supplied DN25 meters with 4-20 mA HART and SS316 wetted parts. The order shipped in 6 days.
In Nigeria, a diesel distribution depot uses DN50 Econo meters with Ex d protection and local totalizers. The meters run 18 hours per day. We keep spare bearing kits in stock for this customer.
A water treatment contractor in Saudi Arabia uses DN100 SS316 turbine meters for brine transfer at 25 bar. The meters use pulse output and a remote display.
A water utility in Western Australia uses a DN150 Econo turbine meter for bore water totalizing. The flow range is 60 to 300 m3/h.
These cases show the Econo line is not a fixed product. It is a standard platform configured for each liquid and site condition.

FAQ: Econo Turbine Flow Meter Pricing and Selection
Q1: What is the price of a DN50 Econo turbine flow meter for clean water?
A DN50 SS304 body with pulse output costs about USD 320 to 520. Add a digital display and 4-20 mA HART and the price moves to USD 480 to 650 depending on the calibration option.
Q2: Can I use an Econo turbine meter for diesel and gasoline?
Yes. Clean diesel and gasoline work well. Use SS304 or SS316 body with sapphire or tungsten carbide bearings. Specify the pipe size and flow range before ordering.
Q3: What is the delivery time to Nigeria, Vietnam, or Saudi Arabia?
Standard Econo turbine meters ship in 3 to 7 working days after payment. Air freight takes 3 to 6 days. Sea freight takes 2 to 5 weeks depending on port and customs clearance. We pack each meter with foam and export wooden boxes.
Q4: Does the price include a calibration certificate?
Yes. Each meter includes a 5 point water calibration certificate at no extra charge. A dedicated calibration on diesel or glycol costs USD 50 to 120.
Q5: What information do you need for a firm quote?
Send the liquid type, flow range, pipe size (DN), pressure, temperature, output signal, and hazardous area classification. We reply within 12 hours with pricing and lead time.
