APPLICATIONS

Start with the measurement task.

Pipeline monitoring

Define the pressure range, medium and connection.

Pumps and water systems

Include pressure limits and installation conditions.

Process vessels

Review pressure reference and medium compatibility.

Common questions

Can outputs and specifications be combined freely?

Configurations across versions cannot simply be combined. Specify output, supply, accuracy and connection for review as one configuration.

Can this replace an existing instrument?

Send the existing model, nameplate, connection dimensions and wiring requirements for mechanical, electrical and process compatibility review.

How do I obtain documents and a quotation?

Email the process conditions, quantity, destination and required document list.
