Wellsite & gathering

Back to the site map

The wellsite round, without the drive.

Wellheads, separator skids and chemical tanks are read on a route: an operator drives to each site, reads the gauges and the sight glasses and writes them down. Waltero reads the same instruments at a set interval, so tubing pressure, vessel level and tank stock are a trend in Mimir, and the route becomes the exceptions instead of every site.

Wellsite & wellheadSeparator & process skidChemical injection

Wellsite & wellhead

The gauges on the tree, read on schedule instead of on the drive.

A wellsite has a handful of instruments that decide whether it is producing: tubing and casing pressure gauges on the tree, the flowline gauge, a chemical tank, the pumpjack itself. Most are read on a route, by an operator who drives to each site in turn. Waltero reads the same gauges at a set interval, so a change in pressure or a pumpjack that stops shows up as an alarm, and the route becomes the exceptions rather than every site.

What we monitor

  • Tubing, casing and flowline pressure

    The existing pressure gauges on the wellhead read in place, at the interval you set, with alarms on a rising casing pressure or a falling tubing pressure.

  • Pumpjack running or stopped

    Run events and run time from a vibration fingerprint on the pumping unit, so a unit that has stopped is an alarm the same hour rather than a finding on the next route.

  • Site tanks

    Vision AI reads the sight glass or level gauge on chemical and holding tanks at the site.

  • Local controller displays

    The figures on the pump-off controller or site panel, read on every check without opening the cabinet.

  • Site condition, with proof

    A photo with every reading: the pumpjack, the tree and the ground around them. A stain under a fitting, a frozen gauge or an open gate is seen on the next check, not the next visit.

Pipeline & compression

Back to the site map

Compressor stations and valve sites, on a trend.

Compressor stations and the block-valve, pig-trap and metering sites along the line are visited on a schedule, and between visits a slow change is invisible. Waltero reads the pressure gauges, the sight glasses, the meter totals and the controller displays at a set interval, outside the unit's own control system, so line pressure and station condition are known between visits.

Compressor stationPipeline & metering station Pipeline & compression assets

Compressor station

Suction, discharge and the cooler, on a trend.

A compressor station is checked on a schedule: suction and discharge pressure, oil pressure and level, cooler temperatures, the hour meter, the panel. Between visits, a slow change is invisible. Waltero reads the same gauges and panel displays at a set interval, outside the compressor's own control system, so the station's condition is a trend rather than a set of visits.

What we monitor

  • Suction and discharge pressure

    The station's pressure gauges read in place, with alarms on drift and on a differential that leaves its normal range.

  • Lubricant and coolant levels

    Vision AI reads the sight glasses on the oil and coolant systems, so a top-up is planned rather than discovered.

  • Cooler and cylinder temperatures

    The existing thermometers and temperature displays read at a set interval.

  • Unit controller display

    Hours, alarms and the figures on the compressor controller, read on every check without connecting to it.

  • Compressor and cooler fans

    Run events, run duration and trends from a vibration fingerprint, with an alert on deviation from the normal pattern.

Storage, terminals & processing

Back to the site map

Tank stock, rack meters and the field gauges the control system does not see.

At the terminal the stock is known when the gauger has been round; in the plant, hundreds of field gauges sit outside the control system because wiring them never paid back, and are read on the operator round instead. Waltero reads the level gauges, the rack and transfer meters and the field instruments at a set interval, so stock, throughput and a drifting gauge are current in Mimir and in the historian.

Tank farm & loading terminalRefinery & process plant Storage, terminals & processing assets

Tank farm & loading terminal

Tank levels and rack meters at the interval you choose.

A terminal's stock is known when the gauger has been round: level gauges on the tanks, the loading-rack meters, the pump gauges, the tank-heater temperatures. Waltero reads the existing gauges and meter displays at a set interval, so stock, throughput and the state of every pump are current in Mimir and in the terminal system, and a tank that is not moving as expected is an alarm.

What we monitor

  • Tank level gauges

    Vision AI reads the mechanical level gauge or sight glass on each tank; high and low alarms at the levels you set, and a level moving with no transfer flags a loss.

  • Loading-rack and transfer meters

    Totals from the rack meters and transfer-line meters read on every check, for reconciliation against the tank movements.

  • Pump and manifold pressure

    The gauges on transfer pumps and manifolds, with alarms on a closed valve or a failing pump.

  • Tank and product temperature

    Thermometers on heated tanks and product lines read at a set interval, for the volume correction and the heater's health.

  • Transfer pumps

    Run events and run time from a vibration fingerprint on the transfer pumps, with an alert on a changed pattern.

Utilities, safety & environmental

Back to the site map

Fuel, fire water and the environmental log, kept current.

The utilities, safety systems and environmental points at a site are checked when someone is there: the generator's fuel and hours, the fire-water tank and header pressure, the pit levels and the discharge meter. Waltero reads them at a set interval with a photo on every reading, so a fuel delivery is planned on the level, readiness is documented between inspections and the permit report writes itself.

Site utilities & powerFire water & safety systemsProduced water & environmental Utilities, safety & environmental assets

Site utilities & power

The generator, the fuel and the air, all on one round.

Every remote site depends on utilities that nobody watches: a generator with a fuel tank and an hour meter, an air compressor, a cooling unit, a battery bank. They are checked when someone is there. Waltero reads the fuel level, the gauges and the panel displays at a set interval, so a fuel delivery is planned on the reading and a utility that stops is an alarm rather than a surprise.

What we monitor

  • Fuel tank level

    Vision AI reads the fuel gauge or sight glass, with a reorder alarm at the level you set and a falling level with no runtime flagged as a leak or theft.

  • Generator and UPS panels

    Hours, load and alarms from the generator controller and the UPS display, read on every check.

  • Air and cooling gauges

    Pressure gauges on the compressed-air system and temperature gauges on cooling units, read in place.

  • Site electricity

    Consumption from the site meter, read at the same interval as everything else.

  • Generator and compressor run events

    Run events and run time from a vibration fingerprint, with an alert on a changed pattern.

Technical specifications

Back to the site map

Built for plant rooms, not server rooms.

What the operations, instrumentation and IT teams ask before a first installation, in one place. Everything here applies to every reading point across your sites, from the wellhead gauge to the terminal's rack meter. ATEX certification is in validation and not yet available: until it is, sensors are installed outside classified zones, which is where most tank gauges, metering cabinets, utilities, fire-water and produced-water points sit.

What it reads
Mechanical and digital meters, pressure and temperature gauges, level indicators, display panels and status lamps. Anything a person can read, the camera can.
How it reads
A photo of the instrument at each interval, read on the device by Waltero's edge AI. Only the value is transmitted, never a video stream; the image behind any reading is available for audit.
Reading interval
Configurable per sensor in Mimir, from every 15 minutes to once a day. Hourly is the usual default for station gauges and tank levels.
Mounting
Hinged adapter over the existing instrument. No plumbing, wiring or modification of the asset; the meter stays readable by hand.
Power
Battery powered, 10+ years at typical intervals. Batteries are replaced by removing two screws.
Environment
Sealed IP68 housing engineered for wellsites, valve chambers, tank farms and outdoor cabinets.
