Product Description

IMP+ I.S. is part of the Pulsar Measurement IMP family, a combined transducer and controller range in one self-contained unit. The IMP+ I.S. unit is certified to ATEX standard EEx ia IIC T4 and IECEx and available with the wetted parts in PVDF, making it ideal for measuring in corrosive or aggressive applications or anywhere where you need an accurate and reliable level measurement. The IMP+ I.S. benefits from our specially designed digital echo processing technique. The IMP+ I.S. are availble in three sizes from 3 m to 10 m (10 ft to 33 ft). With the benefit of the on board LCD display and keypad the IMP+ I.S. is straight forward to set up using the menu led programming.

• Tank Level Applications
• Chemical Dosing
• Simple Level Indication
• Open & Closed Vessel Level Requirements
