Description
The Greyline PSL 5.0 is a pump station level controller that measures liquid level with a non-contacting ultrasonic sensor mounted above the surface. Its six programmable relays handle pump or valve control with alternation and sequencing, level alarms, autodialers and fault alarms, and it records pump runtimes.
With the standard PZ34 sensor it reads to ±0.25% of range or 2 mm over 9.8 m, gives an isolated 4–20 mA output, and runs from 100–240 V AC or 9–32 V DC in a NEMA 4X enclosure. Intrinsically safe sensors and an explosion-proof enclosure are available for hazardous areas.
Argonmark Ltd supplies Greyline instruments across Bangladesh — Dhaka, Chattogram, Gazipur, Narayanganj and the gas fields, refineries, terminals and power plants beyond. Send us the model, range, process connection, output and any hazardous-area requirement, and we will confirm the right configuration, lead time and price.
