Braun HZ5-DR Digital Heating Oil Meter, 0.7 - 40.0 LPH

Braun HZ5-DR Digital Pulse Meter

Oil meters, with Digital Counter & Pulser, and rugged metal exterior

Calibrated, EU Qualification Approval Number D01.5.223.03. Calibration Validity 10 Years

IMPORTANT - All meters must be fitted with a pre-filter of 100 Microns, Maximum. Ingress of particles over 100 microns may lead to wear and or jamming of the movement, and will not be covered by Warranty

Meters are supplied as standard with BSP Female threaded ports, pointing both outwards and downwards from the underside of the meter.

Pulse Output

Connection via screw-clamp terminals
Reed contact: max. 30 VDC | Imax = 6 mA
Rs = 4.7 K-Ohm/0.6W (observe polarity)
Principle: The power circuit of a counter or other registering device attached to the plus and minus terminal clamps is closed via the reed contact and 4.7 K-Ohm impedance. The input impedance should be at least 50 K-Ohm to ensure that the additional counter reaches its switching threshold.
Pulse value: 1 pulse = 0.02l | 50 pulses = 1l
Maximum frequency at 60l/h approx. 1Hz (Due to the reed contact [-debouncing-], use remote counter with dampened input)

LCD Counter

6-digit with 0.1 l display resolution
3V/950 mAh lithium-ion battery
Lasts at least 9 years (depending on temperature and moisture)

Environmental Conditons

0 to 60 degrees Celsius
Max. 85% RH, non-condensing
CE-compliant electromagnetic compatibility
DIN EN 61326-1 2006-10 version

Function of Counter and Pulse Generator

The 6-digit LCD display with 6mm high figures has a display resolution of 0.1 litres (1 decimal point).
A built-in 3V/950 mAh lithium battery supplies power. Its operational life is approx. 9 years.
The internal reed contact supplies 50 pulses per litre, or 20ml per pulse, to the output clamps. The electronics in the counter turn this into a decadic value with 0.1 litres after 5 pulses in order to operate the counter.
Due to the 4.7 K-Ohm internal impedance, a connected remote counter should have an input impedance of at least 50 K-Ohm.
The mounting instructions must be observed without fail if an additional counter is connected to the output.
