Differential pressure (DP) transmitters measure the pressure drop across filters, strainers, membranes and orifice plates — making them essential for condition-based maintenance, flow measurement and level in sealed tanks. A rising DP across a filter is the earliest, cheapest warning that it needs cleaning; a calibrated DP across an orifice is a reliable flow signal.
Condition monitoring, flow and sealed-tank level.
DP across a filter, strainer or membrane rises as it fouls — the trigger for backwash, cleaning or cartridge change. Core to self-cleaning filters.
DP across an orifice plate or venturi gives flow via the square-root relationship — a proven flow method on clean fluids.
DP between top and bottom tappings measures level in pressurised/sealed vessels where a single transmitter can't.
Trended DP drives maintenance by condition, not calendar — feeding the PLC and reports.
A single DP transmitter across a filter pays for itself by avoiding both premature cleaning and blinded-filter bypass — pure condition-based maintenance.
For filter monitoring, flow or sealed-tank level — tell us the application and we will specify the DP cell, manifold, seals and signal and integrate it into your control system.
