FLOW MEASUREMENT · HONG KONG, CHINA
Electromagnetic & ultrasonic flow meters, sourced from audited factories in China
DN10–DN6000. A calibration certificate with every unit. 15–25 working days. Typically 30–40% below comparable European-brand pricing.
PRODUCT RANGE
Flow meters we supply
Sourced from audited Chinese manufacturers and supplied with individual factory calibration certificates. Remote/split, insertion and battery-powered variants available across the range.
Electromagnetic flow meters
EMF-01 Compact electromagneticDirect-reading meter for conductive liquids. Rubber or PTFE lining, stainless steel 316L electrodes as standard.Diameter DN10–DN1000 · Lining Rubber / PTFE · Output 4–20 mA, RS485 · Pressure 1.6 / 1.0 MPa
EMF-02 Remote / split typeSame measuring range as the compact type, with the converter mounted separately — for hot lines, confined spaces or hard-to-reach reading positions.Diameter DN10–DN1000 · Converter up to 30 m from sensor · Output 4–20 mA, RS485 · Price same as compact
EMF-03 Insertion typeFor large-diameter mains where a full-bore meter is uneconomic. Installs through a single tap; available retractable for live insertion.Diameter DN150–DN1600 · Single tap, retractable · Output 4–20 mA, RS485
EMF-04 / EMF-05 Battery-poweredFor metering points with no mains supply. No cabling, no civil works. Available with local data logging or remote telemetry.Diameter DN10–DN1000 · EMF-04 battery, RS485 logging · EMF-05 battery + GPRS/GSM · Best for district metering and remote sites
Ultrasonic flow meters
USF-01 Clamp-on, wall-mountedMounts on the outside of the pipe. No pipe cutting, no shutdown, no process interruption — which makes it the practical choice for retrofit and verification work.Diameter DN15–DN6000 · Accuracy ±1% · Converter + 3 sensor pairs · Shutdown not required
USF-04 Portable clamp-onHand-held unit with built-in data logger. Covers the whole range with one kit, so a single instrument serves survey, commissioning and troubleshooting work.Diameter DN15–DN6000 · Accuracy ±1% · Converter + 3 sensor pairs · Built-in data logger
How the clamp-on kits cover the full rangeEach clamp-on meter is supplied as a complete set — one converter and three pairs of sensors, which together cover DN15 to DN6000. You do not need to specify a sensor size with the order.Small sensor DN15–DN100 · Medium sensor DN50–DN700 · Large sensor DN300–DN6000

WHY US
What you actually get
Not a catalogue reposting factory photographs. We buy from the factories we sell from, and we put the numbers in writing.
Calibration certificate with every unit — traceable and issued against your order number, not a generic sample.Audited factories only — we inspect the production line before we list a supplier.Sample before you commit — a sample unit ships before the bulk order.15–25 working days — lead time stated at quotation, not after deposit.12 months warranty — from shipment, with spare parts held in Hong Kong.Remote technical support — commissioning and troubleshooting by video call.
APPLICATIONS
Where our meters are used
Water distribution and district metering
Wastewater treatment plants
Irrigation and agriculture
HVAC and chilled water
Chemical and pharmaceutical dosing
Food and beverage processing
Mining and slurry lines
Pulp and paper
Clamp-on kits fit existing pipework without a shutdown, which makes them the usual choice for retrofit and verification work.
ABOUT
Dymatech Global Limited
Dymatech Global Limited is a Hong Kong based sourcing company working with audited manufacturers in mainland China. We started in standard water treatment components and now focus on the flow measurement instruments our customers kept asking for.We are a sourcing partner, not a trading desk. We visit the factories, we run the samples, and we hold the spare parts. When something needs commissioning support, you talk to the same people who placed the order.Every unit ships with a factory calibration certificate traceable to your order number.
