News & Innovations


S3C - our new versatile calculator is built on the modularity of the SensoStar family and thus gives you absolute flexibility in the purchase of your needed devices, while reducing your stock-holding costs by a minimised amount of variants.

In future, you can combine any component and you choose the suitable flow meters and temperature sensors just along your needs.

For the new calculator you can plug in or order from the factory the same modules (for example, Wireless M-Bus) for data transmission as with the SensoStar compact meter and thus flexibly set up your warehouse. In addition, you can decide in advance whether you would like to order a device with parameterized impulse values or use the manually adjustable version TX. In this case, you can set up yourself which pulse value the device should have.

Easy connectivity to a smart meter gateway:

Like the SensoStar, the SensoStar C is the calculator for the future through OMS-compliant encryption with OMS 4 Mode 5 and OMS 4 Mode 7.

Engelmann Connect – modular AMR system for end-to-end solutions

Engelmann perfects its product portfolio with its brand new gateway and thus provides the basis for the AMR system, which offers metering service providers tailor-made solutions to master the challenges of the forthcoming energy market.

Engelmann gateway
The Engelmann gateway can be run by both, battery and power supply. So it is suitable for a monthly and a biweekly readout as well as for monitoring. Easy upload of the accumulated data on any FTP server or easy emailing make it very convenient. You choose the data format between CSV and XML.

Simple transition from walk-by to AMR
Existing properties don’t have to be re-parameterised as the gateway can receive and process both long and short, OMS-conform, telegrams. Likewise, devices with unidirectional radio according to OMS version 4.0.2 can be integrated into the gateway. An export function prepares the data for all prevalent billing systems.

SensoStar – The new generation of heat meters for submetering and metering
Given the modifiable casing of the calculator and refittable modules it is the right meter for many occasions. You can customize the meter in a few quick steps with different interfaces such as wireless M-Bus or M-Bus, both optionally with 3 pulse inputs, or with 2 pulse outputs.
You can easily switch the radio telegram from OMS 3.0.1 to OMS 4.0.2. This guarantees a fast transition and connection to a smart meter gateway.
SensoStar can be installed in either forward or return flow. Due to simple parameterisation it can be done immediately on-site by keystroke or using the device monitor. The same way the displayed units can be changed. Meters with a glycol medium can also be programmed on-site by glycol type and glycol concentration.
Engelmann extends its dynamic temperature measuring cycle to 2/60 seconds. All SensoStar meters provide backflow detection, indicated by a direct hint on the display.
