I'm looking for a concrete flow meter that can measure both volume and pressure. It's essential that the device is reliable and accurate for our projects. Could you provide me with details on the models you offer that fit these specifications? Additionally, I would appreciate information on pricing, lead times, and any certifications or standards your products meet. If you have any product catalogs or datasheets, please send those along as well. This will help us in our evaluation and decision-making process. Thanks!
