Metering technology and sensors

All that is measurable

deZem offers a comprehensive program for metering technology in the field. It combines its own hardware with components from third-party suppliers as required in order to connect any desired time-dependent metering quantity. With almost 20 years of experience in the creation and implementation of metering concepts as well as the reliable operation of metering technology, we always find a sound and future-proof solution for the respective objective.

The structure of the field level with deZem offers advantages such as:

  • Metering concepts and installation from a single source on request
  • Data logger iPCX and Edge Controller iPCR to connect existing meters elegantly and securely
  • Particularly flexible and compact meters for electrical quantities
  • Modules for standard signals such as 0 - 10 V, 4 - 20 mA, status and count pulses
  • Sensors for any other metering quantity
  • Integration of existing meters and metering technology
  • Flexibility in the use of standard protocols such as Modbus, BACnet, M-Bus and many more

Questions about specific sensors, the integration of existing systems, etc.?

Multi-Meter ZMx

Flexible metering of electrical quantities

The ZMx family of multi-meters for the flexible acquisition of electrical quantities in the low-voltage range is deZem's own development. Via Modbus RTU, both instantaneous and average values (configurable interval) are available - a total of 116 metered values per device with eight converter inputs. Alternatively, the data can also be acquired and transmitted on an event-based basis. A ZMx records the following variables, among others:

  • Electric active loads [W] and quantities [Wh]
  • Effective currents [A] and voltages [V]
  • Power Factors [CosPhi]
  • Mains frequency [Hz]

The ZMx family has the following members:

ZM8C-P: Basic module with 8 inputs for ultra compact deZem current transformers, expandable with up to 20 ZM8C; this results in 168 converter inputs with a well-structured, space-saving design.

ZM8C: Compact expansion module for 8 additional current transformers each

ZM8C-H: Basic module 8 inputs for current transformer and extended voltage range: L1, L2, L3 to N each 90 - 440 VAC

ZM4R-H: Basic module with 4 inputs for Rogowski coils and extended voltage range: L1, L2, L3 to N each 90 - 440 VAC

Ultra-compact current transformers

Seamless installation

High-quality, foldable current transformers, ideally suited for current metering and monitoring up to 500 A per wire. Extremely compact dimensions allow the use even where other transformers cannot be accommodated. These converters can be connected to a ZMx in groups over greater distances and in any combination by means of practical plug connections.

  • High converter ratios
  • Metering of all electrical quantities
  • Use in main and sub-distribution systems as well as directly on systems
  • Metering accuracy better than 1%, even at a distance of 100 m from the meter

Sensors and more meters

We offer the following sensor, among others, for

  • temperature
  • air humidity
  • CO2 concentration
  • weight
  • Air pressure and flow
  • Ultrasound (flow)
  • Vibration and structure-borne sound
  • Electric current (current transformer & Rogowski coils)

In addition, we offer recording modules and converters for any digital and analog signals such as counting pulses, status messages, 0 - 10 V, 0 - 20 mA, 4 - 20 mA, thermocouples and much more.

Connection of any media meter

Each meter with a standard data interface (M-Bus, wireless M-Bus, Modbus, BACnet, pulse, etc.) can be very conveniently integrated into the deZem system together with other metering values using our data logger iPCX or our Edge Controller iPCR, e.g.

  • electric
  • warmth
  • water
  • compressed air
  • vapor
  • vacuum
  • gas
  • oil
