Overview
The DP-420 is a coplanar differential pressure transmitter for orifice and venturi flow measurement, hydrostatic level on closed tanks and filter differential monitoring.
Static pressure rating of 160 bar and an overload capability of the full static pressure on either side protect the cell during valve manifold operation errors.
Square-root extraction, low-flow cut-off and a local LCD with push-button zero and span are standard. The HART and Modbus versions expose sensor temperature and static pressure as secondary variables for condition monitoring.
Every unit leaves the Veltrix service centre in Eindhoven with a factory calibration certificate traceable to national standards. Accredited ISO/IEC 17025 calibration can be ordered with the instrument or added later as a service.
The downloadable datasheet lists dimensions, electrical connection diagrams, ordering codes and the full specification. Installation and operating instructions are supplied in English, German, French and Dutch.

Features
- Priced in your own unit. The unit of measure and the pack quantity in the specification table are the ones the quantity box and the line total are calculated in.
- Your price, not the list price. A signed-in account resolves its customer-group price, and a contract agreed against the account number narrows it further.
- Quantity breaks that show their working. Where a row carries a ladder, every step is on the page before the item reaches the cart.
- Stock you can act on. A live count, a status, and an expected-delivery date on a row that is orderable at zero.
- Documents on the record. The datasheet and the install guide are rows on the product, versioned with it, not links in a paragraph.
- Options resolved on the page. Each axis is a selector, and every combination carries its own number, stock position and price.
Frequently asked questions
Why can I not see a price until I sign in?
Prices on this storefront are account prices. Signing in resolves the customer group you belong to, and any agreement held against your account number, before a figure is shown at all.
Which number do I get if a quantity break and an account price both apply?
The narrower one. A price scoped to your customer number beats a price scoped to your group, and a quantity break is applied against whichever of those resolved.
The row shows no stock but still lets me order it. Is that a mistake?
No. A row can be marked never out of stock, in which case the expected-delivery date on the page is the commitment rather than the shelf count.
Do the options change the part number?
Yes. Every combination of the selectors is a record of its own, with its own number, its own stock position and its own price, and the number updates as you choose.
What is in the documents table?
The datasheet, which restates the specification table in printable form, and the install guide. Both are attached to the record and carry the revision shown in the specification table.
Where do the related products come from?
From relations held on the record itself, in three groups: related products, accessories, and spare parts. A kit lists its members and each member points back at the kit.
