The Liquiport 2000 Ex offers uncompromisingly more security without any loss in functionality and operational comfort, all at an unbeatable price.
Wastewater is a real cost factor for both industry and local authorities. By means of an exact measurement of the pollution factor costs can be made transparent and can then be fairly distributed. Unfortunately it is still a fact that even today illegal discharges of highly polluted wastewater still need to be identified. In these cases a mobile water sampler with a connected flow meter is applied. These are then suspended into a manhole shaft.
There is always the potential danger that explosive gases can be found in the sewer network.
In the past bad, if fairly rare, accidents have led to many operators defining their sewer systems as Ex zone 1 hazardous areas. Naturally this also has a knock on effect on devices such as automatic water samplers that need to be installed inside the manhole shaft.
It is a fact that with devices that are available on the market today it has always been necessary to install certain functional modules in large, heavy pressure encapsulated housings. However these devices become very awkward to handle, very heavy and almost impossible to operate.
Here we can see the decisive advantage of the Liquiport 2000 Ex concept. Quite simply all the critical components of the unit were individually protected. By doing this the standard design concept of the unit remains almost unchanged. The user profits by the simple operation and unlimited functionality that is offered by the standard unit.
The first impression that the Liquiport 2000 Ex sets new technical standards is convincingly demonstrated. One of the first things that stands out is the black housing. This is due to the graphite mixture in the plastic used in order to achieve a minimum prescribed conductivity. Gas pressurised levers assist in opening the housing brushed stainless steel cover.
The unit operates independently of any power supply using an integrated battery. An expensive separate battery pack is not required thus simplifying unit operation.
Samples are sucked (suction height 6 metres, optional 8 metres) then dosed using the peristaltic pump and then distributed into defined sample bottles. In the simplest form sampling is done time proportionally. The unit also has an analogue input and two digital in- and outputs. This means that the samples can be taken proportionally to a measured flow or on an active input signal, for example on an alarm set point violation. In addition to the sampling actions and messages the integrated data logger also stores and documents the analogue value.
The various sample distribution systems are totally compatible with the standard device and therefore exchangeable. The lower compartment holding the sample distribution can be separately transported. With a total weight of only 25 kg the Liqui-port 2000 Ex can be mobile applied and is easily transported.
