1. INTRODUCTION

Application

The DMSP400 and DMSP500 compact ultrasonic level transmitters from

DELTA MOBREY are an excellent tool for the level measurement of liquids.

Level measurement technology based on the non-contacting ultrasonic

principle is especially suited for applications where, for any reason, no

physical contact can be established to the surface of the material to be

measured.

Such reasons may include corrosive attack by the process medium against

the measuring device material (acids), possible contamination (sewage) or

particles of the process medium adhering to the measuring device

(adhesive materials).

Principle of Operation

The ultrasonic level metering technology is based on the principle of

measuring the time required for the ultrasound pulses to make a round trip

from the sensor to the level to be measured and back. The sensor emits an

ultrasonic pulse train and receives the echoes reflected. The intelligent

electronic device processes the received signal by selecting the echo

reflected by the surface and calculates from the time of flight the distance

between the sensor and the surface which constitutes the basis of all output

signals of the DMSP400 and DMSP500.

A Total beam angle of 5–7at -3 dB as is featured by most of DELTA

MOBREY’s transducers ensuring a reliable measurement in narrow tanks with

uneven side walls as well as in process tanks with various protruding objects.

Furthermore, as a result of the narrow beam angle –the emitted ultrasonic

signals have an outstanding focusing –deep penetration through gases,

vapour and foam is ensured.

corresponding to

Dead Band is a feature common to all ultrasonic level meters.

It is specified as “Minimum measuring distance” in the Technical Data Table.

Measurement within this range can not be interpreted.

Minimum measuring distance (Xm) is determined by the design of the unit within which the measurement is not possible (Dead Zone). This distance can be

extended by programming in order to avoid disturbing effects of possible disturbing echoes coming from fixed objects. (Close-end Blocking).

Maximum measuring distance (XM) is the greatest distance (determined by the design of the unit) which can be measured by the unit under ideal conditions.

The maximum measuring distance of the actual application (H) must not be greater than XM.

2.5 SPECIAL CONDITIONS OF SAFE USE

•Intrinsically safe units with Ex ia IIB marking can only be used in certified intrinsically safe loops with the previously given technical data.

(see values in Additional data for Ex approved models under Point 3)

•The PTFE transducers are made of plastic that can be loaded electrostatically therefore:

–Filling and emptying speed should be selected according to the medium

–Fog development of the dangerous material during filling should be avoided.

–Cleaning of the plastic enclosure is not allowed in hazardous space.

•Equipment with plastic housing are susceptible to electrostatic charges, thus the devices must be protected against electrostatic charges.

•The aluminium content of equipment with metallic enclosure exceeds the limit, the devices must be protected against impact and friction effects.

•The device can be mounted into tanks with up to 3 bar process pressure. The apparatus is not suitable as a fire resistant barrier between the inside and

the outside area. After mounting the unit, pressure test of the system should be carried out on a regular basis in accordance to the local regulations at

1.5 times higher pressure than the nominal pressure value.

•Devices should be grounded by connecting their grounding screws to the equipotential system.

•The device should read or programmed through IR port only outside of the explosive hazardous atmosphere because the infrared interface connected

to the computer is not an explosion-proof apparatus.

2.6 MAINTENANCE.REPAIR,AND STORAGE CONDITIONS

DMSP400/500 units do not require maintenance on a regular basis.

The need for cleaning of the sensor head may occur. Cleaning should be performed by utmost care where scraping or denting of the transducer have to be

avoided.

Repair under or after the guarantee period should only be carried out by DELTA MOBREY. Devices for repair should only be returned duly cleaned and

disinfected.

Unused devices must be stored within the ambient temperature range specified in the technical data, with a maximum of 98% relative humidity.

Software upgrade

Based on the observations & needs of our customers DELTA MOBREY constantly improves and revises the operating software of the device. The software can
