E+H Deltabar FMD72 Electronic Differential Pressure System – Level, Volume & Mass Measurement | ±0.07% Accuracy

The E+H Deltabar FMD72 is a state-of-the-art electronic differential pressure (DP) measurement system designed for precise monitoring of pressure, level, volume, and mass in pressurized tanks, distillation columns, and evaporators. By using two high-accuracy digital sensors (HP & LP) to measure hydrostatic and head pressures, the system calculates exact level measurements in the transmitter, eliminating common issues with traditional mechanical DP installations.

Pre-purchase inspections

are welcomed during normal business hours upon appointment scheduled in advance. We would be happy to provide a complimentary transportation pick up from DFW Airport and back if you want to fly in and see/send someone to inspect the item in person. In addition, we can do Facetime/teams / Zoom calls to go over the skid in person for any domestic /international procurement. Please keep in mind that we are in Dallas and therefore are on the US Central Time (CT) for any communication arrangements.

Shipping Arrangements: The unit is currently located in our yard South of Dallas, Texas. We can assist with shipping arrangements and when properly scheduled, we will provide loading service at no additional charge.

Payment: Payment in full FOB for our yard in South Dallas is required for equipment procurement. We prefer meeting people buying our equipment in person to discuss all aspects of the project requirements and ensure adequate sales support to set your project up for success. We will require a verifiable Cashier check as a payment if you are planning to come in person. We will require a wire transfer in full with the transaction cleared the company account before releasing the equipment to any 3-rd party shipper companies. We are here to help and make this transaction as simple as possible, but we will take all necessary measures to protect us and you.

Please feel free to call/contact Gas Equipment 4 Sale with any questions; we will be happy to answer your online inquiries and/or jump on the call to see how any of our available Gas Equipment 4 Sale can help you meet your project needs.
