Flowmeters in hazardous areas often send a 4-20 mA rate signal, but operators also need to know how much has flowed. The Precision Digital PD4-6628 Loop Leader+ calculates and displays both rate and total from that same loop-powered signal, with no separate power supply.
The large dual-line display shows rate and total simultaneously, and keeps an 8-digit total and grand total. The meter is intrinsically safe, with a maximum loop drop of 2.1 V.
Its NEMA 4X, IP65 enclosure mounts on a wall or pipe near the flowmeter, giving a clear local reading for batching checks and daily flow records.
Frequently asked questions
Can the PD4-6628 totalize from a 4-20 mA signal?
Yes. It integrates the 4-20 mA flow rate signal to calculate total and grand total.
Is it suitable for hazardous areas?
Yes. It is intrinsically safe. See the instruction manual for certification details.
