Web Inventory Management

Remote Web Inventory Management/ Vendor Managed Inventory/ VMI  is the use of remote level sensing technology to measure and report the level of any type of substance, to significantly reduce the cost of bulk distribution (fuel, oil, AdBlue) and collection (waste, recycling).

By knowing when a tank needs attention, efficient logistics can be planned and costs reduced. No wasted journeys, panic deliveries/collections or part load returns.

Moreover, service and supply contracts can be won and retained by offering enhanced service levels to end-users and removing the responsibility for them to check their own levels and arrange deliveries/collections.

Personal, process and environmental safety is also protected by avoiding run-outs and overspills as well as maximising margins by avoiding the need to stop production.

PowTechnology offer over 25 years of experience in sensing and instrumentation, empowering the Industrial Internet of Things by connecting sensors to the cloud.

What is Meant by Vendor Managed Inventory (VMI)?

Vendor Managed Inventory is the use of remote level sensing technology to measure and report the level of any type of substance, with data and high or low level alerts accessible from a remote location.

The use of remote level monitoring helps to significantly reduce bulk distribution (fuel, oil, AdBlue) and collection (waste, recycling) costs.  By knowing when a tank needs attention, efficient logistics can be planned and costs reduced. Moreover, service and supply contracts can be won and retained by offering enhanced service levels to end-users and removing the responsibility for them to check their own levels and arrange deliveries/collections.

Usable operating distance (su)

This relates to capacitive sensors. The usable operating point is in the entire allowable temperature and voltage range is between 80 % and 120 % of the effective operating distance.

Categories

Ultrasonic sensor

Ultrasonic sensors use sound waves to measure distance. A sensor would normally be mounted at the top of a tank and direct a sound wave down towards the surface of the product. When the sound wave hits the product it is reflected and returned to the sensor. The greater the distance between the sensor and the product, the longer it will take for the sound wave to travel down and back up again. The sensors calculate this time interval and give a signal proportional to the distance. They also compensate for the changes in the speed of sound due to changes in temperature. Ultrasonic sensors are not suitable for use in all applications. If the product gives off vapours then this can effect the measurement, and if there is foam on the surface then the sound wave will be scattered and the sensor will not receive a signal that it is able to process accurately.

Temperature medium

The temperature range for which a sensor is rated. Applies to the medium (product) to be monitored.

Categories

Temperature gradient

Temperature gradient applies to the range of thermal transfer flow sensors. It is the change of the medium´s temperature within a defined period of time is called temperature gradient. These flow sensorshave a temperature gradient up to 250 K/min. for water. If the change of medium temperature exceeds this value, there will be a malfunction of the flow controller.

Telemetry

What is Telemetry?

Telemetry is the remote measurement or the remote collection of data which can be physical, environmental or biological.

Telemetry is typically used to gather data from distant, inaccessible locations, or when data collection would be dangerous or difficult for a variety of reasons. In telemetry, specialized instruments perform measurements of physical quantities, and store or transmit the resulting signal – sometimes after some initial signal processing or conversion.

Telematics

Telematics is often confused with telemetry. Telemetry can be the remote monitoring of anything, whether it be moving or stationary, whereas Telematics refers to moving objects, such as cars, fuel tanks and the like, and is generally concerned about their whereabouts or location. It is possible to combine Telemetry with Telematics.

Tank Inventory visibility

86% of deliveries are inefficient – the use of remote level monitoring provides tank inventory visibility and helps to significantly reduce the number of inefficient deliveries, dramatically bringing down distribution costs.  As the cost of fuel continues to go up, the demands from customers get greater and as competiton increases the need for remote tank level monitoring has never been higher and the benefits are clear. Having tank inventory visibility can make cost savings immediately with 24% fewer deliveries needed.

  • Reduced distribution costs
  • Lower carbon emissions
  • Improved customer satisfaction
  • Longer term & single source supply contracts
  • Fewer panics & run outs
  • Long term production scheduling, helping manufacturing and purchasing
Reduce distribution costs with tank inventory visibility

Switching voltage

The switching voltage indicates the maximum voltage (including residual ripple) to be switched by the relay output.

Categories

Switching power

The switching power indicates the maximum power that can be placed on the output relays.

Categories

Switching point drift

This relates to capacitive sensors. The operating distances are given for an ambient temperature of 23C. In the permissible temperature range the switching point varies by less than 15 % from the value at 23C. The temperature of the measured object has no influence on the switch point.

Categories

Switching Point

This depends on the type of sensor being deployed. For example, capacitive level sensors react to conductive materials and non-conductive materials with a dielectrically constant Epsilon >1. The switching point depends on the material. When the sensor-tip is immersed in a fluid, a switching command inside the device is triggered. This trigger is set between contact with the liquid and some mm more into the liquid. This distance between the tip of the sensor and the trigger is the nominal switching point. The immersion-distance has a negative sign, e. g. -8 mm. The water content of an object or a liquid has a decisive influence on the switching point. A high humidity content increases the switching point considerably. If the sensor is moistened with conductive materials, its function can be impaired when a conductive film builds up, that electrically connects the sensor electrode with a metallic conducting side. For an ultrasonic sensor the switching point is the distance from the sensor face at which the output is switched on or off.
