Description

Micronics PF333 Portaflow Portable Ultrasonic Clamp-on Flow Meter (Datalogger, RS232/USB)

Product Details:

The PF333 Portaflow range brings simplicity to the non-invasive measurement of liquid flow and hydronic energy. Portaflow offers the user quick and accurate flow and energy measurement with its easy-to-follow menu and simple setup. Results can be achieved within minutes of opening the case!

Compact, rugged, and reliable, the Portaflow range has been designed to provide sustained performance in industrial environments.

Micronics Portaflow PF333

The PF333 Portaflow electronics are housed in a specifically designed enclosure, which incorporates the graphic display, keypad, sensor, and output facility connections. Set-up of the unit is carried out by selecting the options displayed in the main menu and by following the simple instructions in any of the user-selectable languages.

The use of a rechargeable battery allows the unit to be operated for over 14 hours depending on the facilities used. Continuous operation via the PSU is also possible while recharging the battery. Battery status, signal strength, time and date, as well as flow and energy information, are all continuously displayed, keeping the user fully aware of the measurement process.

The Data Logger delivers 100,000,000 data points, 12 named sites, and the ability to download via USB to CSV file and export to Excel. It also logs application details, time, date, flow rate, forward total, reverse total, flow velocity, flow side temperature, return side temperature, temperature difference, power, total energy, signal Quality, signal SNR, and signal status.

How Does it Work?

The Portaflow 333 is a transit time ultrasonic flow meter designed to work with clamp-on transducers, to provide accurate measurement of liquid flowing within a closed pipe, without the need for any mechanical parts to be inserted through the pipe wall or to protrude into the flow system. It takes just a few minutes to install and there is no need to shut down flow or drain the system!

Micronics PF333 how it works.

When ultrasound is transmitted between the transducers, its velocity is slightly increased when travelling in the direction of flow, and slightly reduced when travelling against the flow. The resulting transit time difference is directly proportional to the velocity of the flow in the pipe. Having measured the flow velocity and knowing the pipe cross-sectional area, the volumetric flow can be easily calculated.

Hydronic thermal energy, heat, or cooling load is calculated from a combination of the flow rate and the flow and return temperature difference or delta T to comply with EN1434 section 6.

Free Mainland GB Delivery Over £150

We offer free delivery on most mainland Great Britain orders over £150 (ex VAT).
This applies across England, Wales, and most of Scotland, excluding certain remote or offshore postcodes.

If your order total falls just short of £150, or you’re a returning customer, feel free to contact us — we may be able to offer a discount code or delivery workaround.

📦 UK Delivery Options

We work with both Royal Mail and DHL to offer reliable and flexible delivery across the UK:

  • Royal Mail – Best suited for lighter parcels and for customers in remote regions, including the Highlands, Islands, and Northern Ireland.
  • DHL – Ideal for most mainland UK orders, providing fast, tracked delivery and excellent reliability for time-sensitive shipments.

Our checkout system automatically displays the available delivery services for your postcode and order weight, ensuring you always see the most suitable options.

Note: Heavy, bulky, or freight-only orders will be charged separately.
Our website is designed for quick, transactional purchases rather than bulk or palletised orders.
Please contact us in advance for a tailored freight quotation if your order falls into this category.

⏱ Dispatch & Delivery Timing

We aim to dispatch all in-stock orders promptly, but delivery depends on both when you order and which service you select.

  • UK orders: placed by 2:00 PM Monday–Friday are usually dispatched the same day.
  • International orders: placed by 2:00 PM Monday–Thursday are usually dispatched the same day.

Orders placed after these times are processed the next working day. This means delivery may occur the following day or later, depending on the courier and service selected.

Once dispatched, your chosen delivery service determines how quickly your parcel arrives:

  • Standard services We use Royal Mail Tracked 24 or DHL Parcel as our ‘Standard’ services. They are not guaranteed to arrive next working day.
  • Premium services (e.g. Royal Mail Special Delivery or DHL by Noon) offer guaranteed delivery windows.

If your order is time-sensitive, we strongly recommend choosing a guaranteed service or contacting us before ordering to confirm availability.

Please note: For logistical reasons, we may occasionally adjust the delivery method selected at checkout. For example, smaller items may be better suited to letterbox-friendly packaging or may be at greater risk of delay or loss via certain services. We actively monitor courier and postal service disruptions—including strikes and delays—and may modify shipping arrangements to help ensure timely and secure delivery.

📅 Busy Periods & Delays

We always aim to dispatch promptly, but delivery times may be affected by:

  • Seasonal demand (e.g. Christmas, bank holidays, or industry shutdowns)
  • Courier network delays outside our control
  • Supplier lead times or calibration requirements for certain equipment

If your delivery is time-critical, please contact us before ordering so we can confirm stock and courier availability.

🌍 International Shipping

We ship worldwide using UPS Express Saver® and other trusted global courier partners. All international shipments are tracked and generally dispatched Monday to Thursday to ensure smooth customs clearance and transit.

Estimated delivery times:

  • Europe: 1–2 working days
  • North America: 2–3 working days
  • Asia-Pacific & Rest of World: 3–5 working days

Delivery times vary depending on location, customs clearance, and local courier performance.

💰 Taxes, Customs & Import Duties

International customers are responsible for any applicable taxes, customs charges, or import duties.
These are not included in our product or shipping prices.

Your courier will typically provide a secure payment link for any import charges once your parcel reaches customs.
If import fees are refused and the parcel is returned, we will issue a refund minus all incurred shipping and return costs.
